Abstract Designs of a polarizational, method for and microscope adjunct to
infrared spectrometry. The authors investigate the anisotropy of
absorption and reflection of gypsum crystals in the region 2-11
microns. For a number of bands corresponding to the oscillations
of water molecules and SOq- groups they discover pleochronism and
extension to variously polarized components. They make more pre-
cise the origin of certain bands and give conclusions concerning
the nature of the oscillations bonds in the lattice. Fourteen ref-

Title : Effect of Extraneous Gases on Spectra and Fluorescence Yield of
Vapors of Aromatic Compounds.
Orig Pub: Optika i spektroskopiya, 1956, 1, 110 4, 536-545
Abstract: A study was made of the dependence of spc-ctra of fluorenceEce
yield of vapors of 3.6-tat--araF-,thyldiaminophtalimide, 3-dimethyl-
amino-6-aminophtaliroide, 3-aminophtalimide, and 3.6--diaminoph-
talimide on the pressure of extraneous gases at various tempera-
tures. It is established that the eff-ect of extraneous gases is
not restricted to reinforcement of the f1uo_re_=;cen-_e as a result
of stabilization of the excited molecules, Vnich takes place only
upon excitation by large quanta. During excitation by small quanta
one observes the reverse phenomenon, weakening of fluoreecence.

It is shown that the excitation frequency, at which no changes
occur in the fluorescence yield in the presence of extraneous
gases (called the inversion frequency) coincicip-s with the fre-
quency of the electron transition. The observed phenomena of
the reinforcement and weeakening of the fluoreecence, are explained
by the transfer of energy from the excited molecule to the mole-
cule of the extraneous gas or vice verea. An estimate is made of
the average amount, of energy, transferred upon collision. Com-
parison of the values of the fluorescence yield of solutions and
vapors shows that the action of the solvent on the fluorescing
ability of the dissolved substance is not restricted to a rapid
establishment of thermal equilibrium in the system, which is of
universal character, but exerts also a specific influence.
A method is proposed for separate investigation of the specific
and universal action of the solvent.

ABSTRACT: Some recent American communications (Refs-5-7)'refer to

are mentioned and views are expressed on the possible
concentrations of these vapours. In this paper the results
are described of the first attemDts to determine directly
the content of water vapour in the atmosphere by means of
specially designed spectral apparatus. The operation of
the instrument was described in detail by Keporent, B.S.

into five sections (1.24, 1.409 1.50, 1.88, 2.2 It), the
wave-lengths 1.40 and 1.8811 belong to the absorption bands
of water vapour; utilisation of two bands is provided for
extending the range of the measured water concentratiorns.
The wave-lengths 1.24, 1.50 and 2.211 fall between
individual bands and serve for determining the initial in-
tensities in the bands 1.40 and 1.884 by means of
interpolation. The linear dispersion of the instrument
equals 100 a/mm; the entry and exit slots are 1.5 mm wide.
Illumination of the input slot is effected by means of a
source with a circular emanating surface fitted with a
dispersion plate of magnesium oxide. Experiments carried
out at ground level showed thatin the operating range of
the spectrum, the role of radiation scattered by the sky
is insignificant. The measured radiation is modulated
with a frequency of 850 c.p.s. using as a receiver of the
radiation a cooled PbS photo resistance. After
amplification the signals are transmitted by radio to the
ground. In ;Adition to the basic signals transmitted in
the operating position of the diffraction lattice (which
Oard 2/4 is turned by means of a cam),, calibrating signals are

The respective switching is effected by means of a
commutator which is coupled with the cam for scanning of
the spectrum. The full cycle of the instrument is 2.5 sees
and, therefore the slow changes of the location of the

rays caused by random oscillations of the instrum;eat

the obtained data require further checking, they do

absorption bands.

ABSTBACT: The first of the authors has shown (Ref'.1) that light
gases andt in particular, helium, have an effect on the
intensity, of the electron absorption spectrum of
0-naphthylamine vapours. In a subsequent work (Ref.2) it
was shown that the phenomenon occurs,in vapours of
3-dimethy-lamino-6-aminophthalamide and therefore is of a
quite general nature. The phenomenon takes the fbrm of a
considerable decrease in the absorption coefficient of the
vapours when light gases are added to them but is not
accompanied by a change in the form of the s ectra. The

gas increases. The reduction in the value of the absorp-
tion coefficient ceases at a certain value of z and re-
mains constant thereafter (Fig~.2). It was established that
the limiting value of the ratio e,,,, to s0 reached under
the action of helium decreases when the vapear pressure,
PR t decreases or the temperature increases. Results
support the hypothesis of the existence in the vapours of
intermolecular interactions at "large" distances. From
the energy dependence of the limiting absorption an estimate
is made of the energy necessary for the formation of an
excited st�Lte of a 3-aminoPhthalamide molecule on collision
with a helium atom. Using the example of acetone and benzo-
phenoneq it'is shown that the phenomenon under investigat-
ion is characteristic for most aromatic compounds.

ABSTRACT% Anthracene (1), 3-acetylaninophthaliaide (II), 3-aminophthal-
imide (III) and 3-dimethylamino-6-aminophthalimide (IV) were
used as test objects. The molecules of substance I which has
spectra with partially permitted structure belong to simple
monstomio molecules. in substances II, III and IV continuous
spectra were found which belong to complicated multiatomic
spectra. On transition form II to III and IV a transition from
nodulatiozi.spootra to fading speatra takes place. The device
used in the measurements was already described in an earlier
,paper. The results of the most important investigations are
compiled in a diagram. The values of concentrations belonging
to these curves and the intensities of the bands are compiled

slightly narrows and besides it is displaced toward the side

obtained at a water vapour concentration of 7-37 x 10-7 mol/cm3
and absorption path lengths of 8.8 and 120.8 m. The equivalent
width A was determined by integration of the spectral curves
by means of a planimeter. Dispersion of the spectrograpt was
2.5 cm7l/mm in the region of interest and the beat resolui-ion
was about 0.1 cm-1. A lead sulphide photo-resistance was used
as the receiver. A multiple-passage cell had a construction
similar to that described in Refal?, 18. The cell temperature
was 60 00 in all ex1jeriments. xhe results of measurements for
the 4 025 cm-1 lines are given in Figure 3 in the fo_-m of

and 6 in Figure B. In Figure 4, Curves 1, 2 and 7 show
departures from the general trend. The departures at higher
concentrations (at values of A greater than 0.9 cm7l) are
due to overlapping of'the studied line (4 025 cm 1- ) with its
neighbours as shown in Figure 1. Departures at low concen-
trations are due to a decrease in the line width when the
Doppler width can no longer be neglected as compared with
the collision width. The results of measu;ements of the

ABSTRACT: This effect, discovered by the present author in 19~-5 (Ref 1),
consists of a decrease of the absorption by vapours of aromatic
compounds on addition of light gases (HO, H2, NO, Y2). The effect
is ascribed to collisions with light-gas molecules which causa,
changes in the structure of aromatic Laoloculas accappanisd by a
perturbation of the RE-alectron systm whIch is responsible for
the appropriate absorption band. Tha author gives a brief thaoratical
discussion of these collisions.

ABSTRACT: This abstract is a survey on papers dealing with in-
vestigations of the effect of light gases upon the
absorption of light by the vapors of aromatic compounds
(Ref 1); this effect has been discovered by the author.
Besides, the relation of this phenomenon with the
remote interaction between the aromatic molecules is
inveatigatod. Such intoractions were oboorved alao in
the course of other experiments carried out by the author
and Klochkov (Ref 2). As result of the investiffation
(Refs 1,3,4) a scheme of the observed phenomenon was
suggested. The light gases cause a weakening of the
Card 1/4 absorption in substances that contain chains of conjugate

bonds (save benzene). The collisions with the particles
of light gases cause changes in thestructure of the
investigated molecules; these changes are accompanied
by a violation of their n-electron systems and by a decrease
of the absorption. Because of experimental difficulties
and the limitations of the spectral range accessible
to investigation, which are resulting from these
difficulties, the experiments to discover the structural
rebuilding of the molecules in the transition from the
state N into N' (according to the alteration of the
infrared spectra of the vapor) have not brouaht any
definite results as yet. The totality of experimental
facts allows to assume that the investigated interactions
(Ref 6) are connected with the displacements or other
alterations of the n-electron shells of the molecules.
It is very difficult to study this phenomenon by using
the alteration of the spectra as a vehicle of investigation.
The results obtained from the analysis of the effect of
Card 2/4 light gases upon the absorption by vapor are decisive.

If the coefficient 4. is introduced they allow to
nvestigate the interaction between the molecules
N-N quantitatively. To a certain degree of probability
it can be assumed that these interactions can be
described being of a dipole-dipole type; on this
occasion the theory developed earlier by Vavilov
(Ref 7) and lately by Galan6v (Ref 6) can be applied.
The investigations probably will help to explain the
mechanism of the intermolecular relations N-11 as well
as preventive measures against the Iinteraction with
the atoms of light gases (N+A -4 F+A). There are

ABSTRACT: In this paper the author presents a solution of' the problem of
the relations between the absorption- and luminercence spectra
of molecules, which was obtained by a method, logically quite
opposed to that used by Stepanov (Ref 9). The author proceeded
from the assumption that between the absorption- and emission
spectrum of a system which is in thermal equilibrium there must
necessarily exist certain relations. The information collected
substantiates that the differences in the spectra as demonstrat-
ed in references 1, 2, and 14 are always preserved. For this
reason they will have to be sabjected to further investigation,
just as other differences of the molecales which correspond to
different relations of the spectra. The considerations advanced

types of spectrum cannot be considered to offer a final solution
of this problem. This was also remarked in reference 1. Never-
theless they permit to draw certain conclusions on the nature
of the relations between the spectra and the character of
molecular interactions. Among the results thus obtained the
solution of the problem seems to be essential, whether it is
necessary to take into account the interdependence of the
electron states and of the nuclear structure with the electron
transition of the molecule skeleton and the electron cloud,
respeotively. From this the necessity of a relaxation proceeds.
If this process is taken into account a system of electron
states is derived, which can be represented by a four-level
scheme (Fig 2). The degeneration of such a scheme into a two-
level scheme (Fig 1) is, within the limitations of this study,
a special case for complex molecules, just as is the exact
mirror symmetry of the spectra. Real complex molecules poesess
a system of electron states of the type portrayed in figure 2,
which more or less deviates from the idealized scheme (Fig 1)

frequencies of the emission spectrum is determined only by the
distribution of the molecules on the excited levels and by the
probability of the corresponding transitions, if a forced
emission and an interaction of the excited molecales is practi-
cally absent. Hence the luminescence spectrum under these con-
ditiona must be similar to the spectrum of thermal emission, and

electron state is stabilized with respect to the oscillation
energy. If this relation is not satisfied, it can be proved
that at the moment of emission the distribution is not an
equilibrium one. It then corresponds to a distribution charac-
terized by a temperature TO t T.
B. S. Neporent comments on the lecture held by R. N. Alentsevt
It appears to 6e difficult to approve of the assumption that
the excited molecules in solutions do not reach a thermal
equilibrium in due time. This assumption is at variance with the
experinental data on the transfer rate of the oscillation
energy. Moreover it does not furnish an explanation of the diver-
gencies found in several investigations.
V. M. Agranovich agrees with Stepanov concerning the joint re-
lations between the luminescence- and absorption spectra. He
rejects, however, his conception concerning earlier papers (A.
S. Davydov, S. 1. Pekar, M. A. Krivoglaz, and others) and thinks
that the equation found by him should be compared with the re-
Card 2/2 sults presented by other, earlier theories.

parameters of high-speed spectral apparatus). The highest
speed of recording is obtained with the best inertialess
PbS-receivers using a: circuit breaker. The tendency to develop
higher registration speed with given (thermal or semicon-
ductor-)receivers inevitably leads to a decrease of the re-
solving power as well as to an increase'of temporal dis-
tortions, which is tolerableg howevert only in exceptional
cases. Acocrding to the authors' opinion the so-called appa-
ratus Kr~8 is beat approximated to optimal operational condi-
tions. For a PbS-receiver this apparatus has a rather high
speed (v e-10~') and also the resolving power remains suffi-
ciently good. Above allIthe distortions in this apparatus
are not great. A table gives the publishe#ata on high-speed

ABSTRACT: The XI. Congress on Spectroscopy was held at Moscow from
December 2 - lo, 1957. The program was devoted to physical
problems of atomic and molecular spectra and to the spectra
of solids. The congress was attended by 6oo delegates from
36 cities of the USSR, as well as by 12 foreign scientists
from Great Britain, Eastern and Western Germany, China,
Roumania, the USAp France and Yugoslavia. (The X. Congress
on Spectroscopy held at L'vov in 1956 was attended by about
15oo delegates who delivered 3oo lectures). The XI. congress
was arranged in 7 plenary meetings and 12 sectional meetings,
in the course of which more than 125 lectures were held, 3o
of them dealing with atomic spectroscopy, about 6o with mo-

PERIODICAL: Doklady Akademii Nauk SSSR, 1958# V014 119,

ABSTRACT: According to the author's opinion the problem of mutual re-
lations between absobption spectra and emission spectra of
polyatomic molecules of all types can be solved in the same
manner as in the case of systems with narrow levels: the equi-
librium of molecules with equilibrium radiation is examined,
and in this way the characteristics of the individual molecules
are obtained. These characteristics are then used for the inve-
stigation of the luminescence induced In statlowry conditions.
The author here studies molecules which can be characterized
by modulation spectra. In such molecules the electron states
can be considered to be independent of the oscillation states.
Card 1/3 The conditions for the equilibrium of a system consisting of
General Relations Between Absorption and Emission for 2o-119-4-15/6o
the Modulation Spectra of Polyatomic Molecules
such luminescent molecules with equilibrium radiation are
apparently the following: A) The molecules must be distributed
over normal and induced states according to the lama of sta-
tistical equilibrium. B) According to the existing amount of
oscillation energy the molecules must be distributed over both
electron states. 0) The radiating power of the system investi-
gated must be a product of the aboorptim capacity and the
spectral density of equilibrium radiationt i.e. the luminescence
spectrum must agree with the spectrum of the thermal radiation of
the system. A formula for the condition of equilibrium is
written down. The author then introduces the experimentally de-
termIned quantities into the ekloulation: the molecular ab-
sorption coefficient, the spectral density of the quantum
yield of fluorescence, and the measured life of the inducel
state. The general expressions obtained here describe all
relations existing betweon the spectral absorption and emission
of polyatomic molecules with modulation spectra. These ex-
pressions apply in the same manner to simple polyatomic mole-
cules (in which the structure of the spectrum is conserved) and
Card 2/3 also to complicated molecules. The results obtained here seem,

by the way, to indicate the impossibility of describing the
spectra of atteamAtion by means of the scheme discussed. There
are I figure and 14 references, 12 of which are Soviet.

PRRIODI CAL OpWa I spektroskopiya, 1959, Vol 6, Nr 6. pp 801-803 (USSR)
ABSTRACT: Diffraction-&rating spectrometers were used to determine humidity of
air at various heights of the atmosphere from attenuation of 9olar
radiation in the regions of absorption by water at 1.4, 1.9 and 2.6 IL,
The spectral regions around 1.2, 1.5 and 2.2 IL were used for control
purposes. The various mavelangths were presented successively to the
spactrometer slit by means of a device which uses a cam. The optical
signal war, modulated at 100 c/4 and photoresistors of PbS were used
as receivers (they were supplied by S.P. Tibilov and I.G. Kopilevich').
The instrument used is shown schematically in Fig I where D Is a matt
aluminized plate used as the source. The instrument was calibrated by
means of a special call in Yftich the optical path could be varied from
8 to 100 m, pressure of vater vapour from 0.9 to 10 mm H& and pressure
of nitrogen which imitated atuosphere, from 50 to 500 mn HS. A
Ca rd 1/2 calibration curve for the 1.4 IL region is shmm in Fig 21 it gives the

After reachine; its maximiua height and drifting for a while, the balloon

a parachute. Fran the absorption spectrograms obtained at various heights
the amount of meter vapour in the atnospbere was calculated and it is
given in Fig 5. Humidity of air could be measured at heights up to
11 I= using the b" at 1.4 it,- for higher heights the stronger bands
at 1.9 " 9.6 ii were used. curves 1, 11 &ad III in Fig 3 give the
amount of meter vapour as a function of height determined from measurements
carried out in 1957. 1956 and 1956 respectively. The 1957 dat& for
heights or 11-11 km (curve 1) are not regarded as reliable.

even considerable errors, due to the apparatus function may be amAly
allowed for by an appropriate treatment of the records - If such
treatment was carried out it would not be necessary to include the
apparatus-function contribution to the total error (the term ar,2 in
Eq (81) in RaxAtian's woric, Ref 2). One must ramamber also that In
some cases the contour of the band Is required, In others - its area
and in still others - the intensity at the band maximim and its width.
All these are special cases as Mr as errors are coucerned and this is
also true of rapid methods of recording. Themethod of recording
should be selected bearing in mind all these factors. Consequently a
general formulation of the relattonships between a, v and %, would be
more useful than the suggested "universal" conditions of recording.

TEXTt The present article is an abridged reproduction of a lecture
delivered orL the occasion of the Eighth Conference on Luminesoenag
(Minsk, October 19-24, 1959). The authors-investigated the transfer of
vibrational energy in both directions (absorption and release by excited
molecules) by means of a method which is based on the investigation of
the.dependence of the fluorescence yield of vapors of aromatic compounds
on the pressure of.foreign gases. An intensification of fluorescencell
corresponds to,a stabilization and a weakening to a labilization of the
excited molecules due to absorption or release of vibrational energy in
collisions. The stabilizAtion of excited molecules of 3-dimethylamino-6-
aminophthalimide in coll .:.one with molecules of foreign gases was studied

with regard to its effect on the fluoredoence yield of the vapors of the
matter investigated on excitation of various wavelengths in a large range
of the spectrum. The investigations were made for the following foreign
gasest He, Re, Ar, Krj le; H20 D29 N21 CO, and H20, D20' NH30 and C 5 H12*
The mean vibrational energy transferred to or from the complex molecule
per collision event with a foreign-gas molecule was determined. It was
observed that the mean vibrational energy released by an excited-
3-dimethylamino-6-aminophthalimide 'molecule increases with the mass and
the complex structure of the foreign gas. However, this dependence cannot
be formulated uniformly. A monotonic dependence could be observed only
in monatomic gases; however, also in this case a considerable deviation
from the theoretical dependence was observed, which had been computed
according to a conception of elastic collisions of balls. This shows the
inadequateness of this model. It is assumed that these deviations can be
explained by the fact that an energy exchange takes place not only among
the molecules but also between the internal and external degrees of tK

freedom of the excited molecule of the matter investigated. To study this
phenomenon, the aacomodation coefficient was computed by employing a
formula deduced by the authors in Reft 4 and all degrees of freedom were
taken into account for the energy transfer. It was found that. the
efficiency of collisions with respect to energy trans-for depends monotord-
cally on the van der Waals' interaction constants of the molecules of
foreign gases. An estimate of the part played by rotational and
vibrational degrees of freedom of diatomic and polyatomic molecules
of the foreign gas in energy transformation was given. It was
experimentally found that the reverse process (energy transformation of
the foreign gases into oscillation energy of the molecules investigated)
is much less probable than the direct process. There are 4 Soviet refer-

TITLE. Fluorescence polarisation and the spectral

PERIODICAL: ~ptika i spektroskopiya, v.121 no.2, J962, 233-238
TEXT: The object of this work was to determine the degree
of polarisation in fluorescence in the fluorescence and
absorption spectra of compounds characterised by wide and
structureless bands in their spectra. The authors disagreed with,.-_
-views expressed by G.P. Gurinovich, A.N. Sevchenko and
A.M. Sarzhevskiy, who claimed that with a constant frequency of
the exciting light ,,)e the degree of fluorescence polarisation
P of complex molecules in solutions depends on the frequenc4, N)f
of the portions of fluorescence spectrum in which the measurements
were carried out. The same apparatus and substances were used as
in the previous works. In the apparatus the light from the
source prior to the falling on the sample was passed over the
diffraction grating monochromator and a polarising Glan prism,
and the emerging beam was passed through another polarising

prism, a filter separating the orders, and another diffraction
grating monochromator from which it was passed to the photo-
multiplier with its amplifying and registering circuit. The
parallel and perpendicular components of the luminescent light
were measured with respect to the plane of polarisation of the
exciting light. The measurements included 3-monomethylamitio-
phthalamide in glycerol, 3-dimethylamino-6-aminoplithalamide in
glycerol and also solutions of fluorescein in glycerol. The
fluorescence spectra of the first two substances did not show
the claimed relation between P and -4f, while the last
substance showed the dependence of P on of. The fourth
substance tried, 3-monomethylaminophthalamide in polymethyl-
methacrylate, gave S-shaped curves and the detailed studies
showed that the dependence of P on Vf is,due to the presence
of various types of luminescence centres. Hence it was shown
that the change in the degree of polarisation along the -
fluorescence apoctrum in due to the presence of at least two
luminescence centres with different degrees of fluorescence
polarisation. There are 6 figures.
