Dec 19551 857-863 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- erences: e.g. On Katsumura, Meu. Faculty Sci.

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. Card 1/2 USSR / Optics Abs Jour: Beferat Zhur-Fizika, 1957, No 4, lo403 K 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. card 2/2 Molecule, Chemical bond. BA miya,No 7, 1957, 21978 Author :,Neporent B.

ABSTRACT: Some recent American communications (Refs-5-7)'refer to investigating the spectrum of the Sun in the infrared range during flights in the upper layers of the atmos0ere, in which observation of absorption bands of water vapours. 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. et alii (Ref.8); itO.~qonsists of a step-wise vacuum monochromator with~&! diffraction lattice of 300 lines/mm Card V4 of the size 50 x 70 mm which subdivides the infrared range 49-4-21/23 Experience gained in direct measurement of the distribution of the humidity of the atmosphere by means of the spectral method. 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 49-4-21/23 Experience gained in direct measurement of the distribution of the humidit7 of the atmosphere by means of the spectral method.

Increased accuracy and sensitivity of the instrument for measuring low water concentrations could be achieved by using more intensive absorption bands.

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 qL*~sorptionavefficient E of the VaPoUrS uNer investiga- ti gradu y decreases as the vapour pressure of the added gas increaseav, or, as the number of collisions, z between the molecules of the vapour and those of the added Card 1/? 51-5-10/11 On the Mechanism of the Effect of Light Gases on the Absorption of Vapours of Aromatic Compounds. 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: A preliminary communication on the subject of the present paper was given atthe Tenth Conference an Spectroscopy on July 129 1956. The paper gives the results of measuremen is of the infra-red absorption by a single line at 4 025.38 cm- and by a group of 9 lines in the region 3 970-3 978 cm7l which belong to the -4 3 and -J, bands of water vapour. Concentration of water vapour Cms vLried*XraVL2xJD.-7' to 45-5 x 10-7 201/eM3 and absorption path lengths were from 8.8 to 1G0.8 m. The part of the spectrum containing Vie4025.38 cm-1 line is shown in Fig. 1. The group of 9 lines in the region 3 970 - 3 978 cm is given by arrows in Figure 2, whicJh represents the spectrun Cardl/5 Sov/51-1; 4-7/24 Dependence of the Infra-red Absorption by Water Vapour on its Concentration and on Path Length for the Case of a Separate Lin and for a Group of Lines in the 2.? IL Band 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 dependence of the equivalent width A on VTI - Figure 3 shows that or A from 0.1 to 0.9 cm A is in fact proportional to A linear dependence o A/C on 4-L for the 4 025 cm7l line is shown in Figure 4 for the tango of values of A from 0.1 to 0.9 cm7l. Departures from straight lines in Figures 3 and 4 are observed at low concentrations (Curves 1 Card2/5 sov/51-4-4-7/24 Dependence of the Infra-red Absorption by Water Vapour on its Concentration and on Path Length for the Case of a Separate Line and for a Group of Lines in the 2.7 1z Band and 2 in Figure 3 and at high concentrations (Curves 7 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 square-root law is observed up to values of about 2a--2-5 CM71- In the region of applicability of the square- root law, the angle of slope of the rectilinear portions of curves of Figure 5 is proportional to the squAre root of the concentration of water vapour C. This is confirmed by Oard3/5 Figure 6 which shows dependence of A/C on IT . The black sov/51-4-4-7/24 Dependence of the Infra-red Absorption by Water Tapour on its Concentration and on Path Length for the Case of a Separate Line and for a Group of Lines in the 2.7 U Band circles and the continuous curve in Figure 6 correspond to the rectilinear portions of the Curves 2-5 of Figure 5. Figure 7 repeats the results of Figure 5 in the form of a dependence of A on logkCl) . In this case, the points for values of A [~Teater than 2.5 cm-1are found to lie on a family of parallel lines. Such a logarithmic dependence for absoprticn due to a vibrational-rotational band was first suggested by Elder and Strong (Ref 10). A more precise expression, in which dependence of the line-width on concentration was taken into account, was obtained for "strong" absorption bands of water vapour by Howard, Burc-h and Williams (Ref 9).

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 Effect of Light Gases on the Electron Absorntion Spectra and SC7/48-22-9-1o/-~o the Interaction Between the Molecules of Aromatic Compounds 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.

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).

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 Card 1/3 In references 12 and 1 concerning the generation of the two SOV/48-22-11-20/33 Relation Between the AbsorDtion- and Luminescence Spectra of Polyatomic fdolecules 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) Card 2/3 which has hitherto commonly been used.

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.

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.

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, General Relations Between Absorption and Ecission for 2o-119-4-15/6o the Modulation Spectra of Polyatomic Molecules by the way, to indicate the impossibility of describing the spectra of atteamAtion by means of the scheme discussed.

TITLE: spectral Determination of the Humidity of Air in the Upper Layers of the Atmosphere (Spektrallnoye opredelonlys vlashnosti vozdukha v varkhnikh sloyakh atnoefery) 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 SOV/51-6-6-16/.34 Spectral Determination of the Humidity of Air in the Upper Layers of the Atmosphere reduced absorption as a function of the square root of the amount of mater.

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. There are 2 Soviet references. . Note.

In later work Neporent (Ref.2) suggested that the intensification of fluorescence by foreign gases V43 can be used in studies of energy transfer in molecular collisions. The results reported in!these two papers and in other work (Ref-3 to 9) are reviewed in some detail (Fig,,l to 3). It is shown that in studies of the processes of vibrational energy transformations during collisions of complex excited molecules with foreign molecules, it is necessary to allow for the energy exchange both Card 1/2 s/o5i/60/008/005/007/027 E201/E491 A Spectroscopic Investigation of the Processes of Transformation of the Vibrational Energy of Complex Molecules During Collisions. 1.

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 Card 1/3 LIr 81278 Spect-roscopic Investigation of Vibrational 51048 ,/60/024/05/04/009 Energy Transfer in Interactions of complex B006/BO17 molecules 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 Card 2/3 81278 Spectroscopic Investigation of Vibrational 3/048/60/024/05/04/009 Energy, Transfer in Interactions of Complex B006/BO17 molecules 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.

TITLE. Fluorescence polarisation and the spectral classification of complex molecules 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 Card 1/2 Fluorescence polarisation and the ... S/051/62/012/002/008/020 E202/EI92 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.
