Abstract: A t3wory is given for a miLtilayer polarizer consisting of any
number (m) different non-absorbing thick plane-parallel layers.
A separate analysis "van for the case of identical absorbing
layers. Equations are obtained for the intensities of the.light
beams, reXlected or transmitted through the multilayer pile., and
equations are given permitting calculation of the degiie of
polarization (Pdm) in the absence of aboorption,,using a glass
pile as an example. Its suitability is shown for all the working
range of angles p.. The folloving results are obtaineds

-Abstract: (a). In the Tange 0 4C 11*/Vd~ there is a maxim=,, the position
of vhich abifts as m increases oward the region of smaller
anglesj as m becames infinite it corresponds to the Brewster
angle. (b) At 9 - -1T/2 we obtain Pd. = const, regardless of m.
Tbevalue of Pd~ is determined in this case only by the index of
refraction n. It is shown that the degree of polarization de-
pends substantially on the absorption, leading to-an increase in
Pdm. Investigation of oeleni= p:Ues (m a 1., m V 4) absorbing
in the visible portion of the spectrum (A = 589 *), led to re-
oults that are in good agreement with the calculatediftta. The
authors propose that -the established dependence can be used to
measure the absorption of solid isotropic substances. A de-
scription of the tecbnology of preparing a selentum.pile., in-
tended for polarization of infrared radiation, is given.

Abstract Description of the construction, technology of manufactu-
,re, and test results of an hydrogen arc tube of low pres-
sure. The cathode is a nickel hemisphere 15 mm in radius.
Its internal surface is covered with oxide. Heating is
indirect. The electrons emitted by the cathode are inci-
dent on the anode through an opening 3 mm in diam ter,
made in the center of a molybdenun disk, tightly covering
the cathode hemisphere. The anode is made of a molybde-
num plate in the form of a saucer with an opening in the
middle (diameter 5 M), which is attached to a nickel '
ring. The maximum discharge current without water cooling

is 17 amp, and the current density is 240 amp/cm2.
The most favorable hydrogen pressure is 1.6 -- 4.2 mm
mercury. Increasing the discharge current causes the
radiation intensity to increase linearly, and the ener-
gy distribution over the spectrum remains constant.
The dependence of the discharge current and of the volta-
ge drop across the tube on the change in the hydrogen
pressure was investigated. In the pressure range bet-
veen two and 1;2 mm mercury the tube operates as a rec-
tifier. Increasing the pressure decreases the differen-
ce between the firing and arcing potentials.

ABSTRACT: By thin films, the authors understand transparent or non-
transparent layers whose properties depend on their thickness
and differ from the properties of bulk samples.-, This paper
studies quantitatively the phase-shifts of the reflected light
for films of silver, germanium, tellurium and selenium when
the thickness of these films changes. The phase-shift 6 was
studied on wedge-shaped samples. The samples were prepared by
deposition in vacuum on glass plates. Purities of the materials
deposited were as follows: silver - 99.98%, tellurium - 99.7%t
selenium - 99.5%. The purity of germanium can be inferred
from its besistivity which was 50 Q.cm. The phase-shift is
meas-ired by the method described in Ref;79 Results are shown
in Figs. 1 (silver), 2 (tellurium~,3 (9 rmanJum) and 4 (a elen--
ium). In the figures, the thickness d is giyen in All

Thin-layer Optics I. Phase-shift on Reflection of Light from Thin
Films of Silver, Germanium, Tellurium and Selenium.
Comparison of the four figures shows that in each case, at
the lowest thicknesses, there is a phase-shift minimum. In
addition to that minimum, there is at least one maximum of
phase-shift for each substance. Silver differs from the
other4three semi-conductIng substances by reaching a value
6 . 1.24 at ahout 100 A and this value does not materially
vary,with further increase In thickness. Semiconductors, on
the other hand.. show further,minima and maxima in t1ke phase-
shift with inereaae-in thickness.. These differences may be
re. ated to the structure of the films (it is Imown that
silver and tellurium films are crystalline, selenium and
germanium are-ar4orphous.), The results quoted in this paper
are not sufficient for firm'co.nclusions on this point.

ABSTRACT: There is not much information on the infrared absorpt-
ion of liquids, particularly in those parts of the spectrum
where the coefficient of absor-otion, k , reaches tens of
thousands cid-L . This is mainly due to experimental diffi-
culties ivhich occur when one tries to use the law
I =;I 0 exp(-kd) directly. Already at k = 104cm-1 d is
of the order of a It for kdr-il. No one has managed to ob-
tain such small thicknesses. In the present paper a possible
way of removing this difficulty is considered. If the ab-
sorption of the liquid is large, then, instead of a contain--~
er of the usual type, it is possible to use one which does
not include spacers, i.e., the thin layer of liquid is held
between the plates by surface tension forces. Such a meth-
od has already been used in transmission measurements (Ref.
Card 1/2 3). By regulating the degree of closeness of the plates it

TM-i A combined polarizer, in which each component consists of a three-
layer Ge-Si-Ge film, is described. The theory of this type of polarizer is
kriven, and the results of an experimental study of its optical characteristics
are presented. It is shown that three films are perfectly sufficient for the
full polarization of the light that has passed through. Thus, the polarizing
qualities of the new device are better than those of a selenium pile which is
the most widespread polarizer of infrared radiation. A distinguishing feature
of combined films is their greater mechanical strength as compared with selenium
:films. However, they fall behind the latter as to transparency.

TEXTs Some designs of new rigid polarizers made with Ge are described.
The best characteristics are displayed by polarizers of the interference type
operating on reflectioncr transmission. The most accomplished design of a re-
flecting polarizer consists of two mirrors, whose reflecting elements are pro-
vided by thin Ge layers (d - 1,100 R), applied to a rock salt backing by evapora-
tion in vacuum. This system is characterized by high light-gathering power and
by a degree of polarization that practically attains 100%. About the same char-
acteristlas apply to the most efficient interference polarizer, which operates
on transmission. It consists of a plane-parallel rook salt plate, either face
of which is coated with a thin Ge layer. All calculations and measurements of

harmonic spectra of vapours ivere also obtained. The absorption
spectra were measured using an autocollimating spectro-
photometer IKS-6 at room temperature. Precision of measurement
of the wave numbers and the absorption maxima is limited
primarily by the precision of calibration of the spectro-
photometer (see Table 1). To exclude the effects of reflection,
the measurements were made using pairs of cells; thickness
of one cell in such a pair was approximately double the thick-
ness of the other cell. Thicknesses of cells for liquid CCI 4

ABSTRLCTs The paper gives results of measuremint of the reflection coefficients

These layers were prepared by sublimation as described in Reg 1.
Standdrd methods of measurement of the coefficients of reflection on
tlie air'side (R) and on-the base side (RQ and the transmission
coefficient (T) were eaployed (see Ref 2). The authors used wedge-
shaped platen with 1.52 refractive Index for the sample supports.
The coefficient R, R, and T were measured only for layers produced

layer thickness d was measured independently (Ref 3). The
results obtained way be divided into -two groups. The first group
includes cf. R, Rt , T and absorption A a 1 - R - T. All these
parameters vare obtained by direct measurements and they are subject
to experimental errors only. The second group includes n and K, which
ware calculated using -theoretical considerations, and therefore
their values are affected by the approximations of the theory used.
The results are given in Figs 1-6. In all figures, except Fig 5,

A13STRACT: Such investigations are of paramount importance for
the determination of the factors which influence the
intensity, the half-width, the shape, and the structure
of the oscillation bands. Individual absorption bands
of carbon tetrachloride were chosen by the authors
as vehicles of their investigation. They were studied
at different states of aggregation and at temperatures
near the point of transformation. The spectrum of CCI 4
is at present tho.-oughly investigated and the majority
of frequencies has already been identified (Refs 1,2).
A method which was developed already earlier was used in

intensive double band was investigated as to its temper-
ature dependence. One of the components of this band
(-,j= 784 cm-1) corresponds to the treble degenetated.
fundamental oscillation N)3and the second (-,)= 762 cm
corresponds to the compound oscillation N), +1 4* Owing
to a Fermi resonance this oscillation band attains an
intensity comparable to that of the fundamental oscillation.
For the temperature investigation two isolated doublets
were chosen from several dozens of compound bands. A
Fermi resonance was found to occur between its com-
ponents. The separation of the doublets into their components
is not difficult if both components are assumed to have
a symmetrical shape. The data known at present are by far
insufficient for an explanation of the temperature de-
pendence of the intensities of the bands of infrared
absorption and are even more inadequate for a conotvuction
of a theory which agrees with the experimental evidence.
Influence of Temperature and of the State of SOY/46-22-9-29/4,o
Aggregation on the Infrared Absorption of Carbon Tetrachloride
The only statement which can be made must be limited
to the fact that in this case a temperature reduction
leads to decrease of the matrizelements of the transitions.
The magnitude of the latter is not only dependent
upon the type of molecule but also upon its surroundings.
Supplementary investigations were carried out in order
to determine the influence of the state of aggregation
upon the intensity of the compound absorption bands.
A computation of integral intensities has shown that
I(,,d, is reduced by almost to half its original value
for the long-wave component of each doublet at the
transition from liquid to vapor. With short-wave com-
ponents and in particular with the band \), +J) 3 this
reduction is insignificant. The weakened resonance

ABSTRACT: The first part of the paper presents a rather inconclusive
theory of deposition from an evaporator (Fig 1 and
Eqs (1) - (121)); the results from this theory, which
give the thickness C as a function of the angle cc, have
to be checked by some independent method in the first
instance. The equations from (11") to (14) deal with
one way of checking the results; thicknesses d, and d2
are measured at two different points. The equations
down to (17) introduce corrections for non-sphericity
of the source. The next section deals with cylindrical
sources rather briefly. Fig 2 shows d and CU) (curves

ABSTRACT: The method described here is based on reflection and is
intended for use with liquids. The cells are hermetically
sealed in order to eliminate interference from the vapour
(the.examples given relate to CHGl and CC1 ). Fig 1 shows

reflection curves for Cel 4 near 12 IL; the top curve is for
a properly sealed cell, while the bottom one relates to a
cell with a vapour leak. The window used to seal off the
liquid is an optically worked plane-parallel plate (e.g. of
rook salt); Eq (1) gives R , the measured reflectin
(,g power,
in terms of I. (the reflected intensity) and Io he
incident intensity), or in terms of R12 (the reflection
coefficient at the outer surface of the plate) and of R23
(the reflection coefficient at the inner surface). Eq (2)
gives R12 as a function of n . which is known accurately

ABSTRACT-s. Voltkenshtdyn, Yellyashevich and Stepanov's theory (Ref 1) of the
temperature depedence of intensities of vibrational absorption bands
has not yet been verified, because of great experimental difficulties.
The present note reports the first attempt at verification of this
theory for the combination frequencies V, + 1~6 and Yl + (Y1 + V4) of
gaseous 0014. The theoretical temperature coefficiints for these
vibrations are given by Eq (1). The ex.pressions of Eq (1) can be used
to construct theoretical curves but their comparison with experiment is
difficult because the bands V, + -06 and 1), + (V 1 + -d overlap strongly
forming a aloes doublet. For this reason the total Ltegral absorption
of the doublet Yes determined and compared with the corresponding
calculated curves. The absorption curves cf the doublet were obtained

SOV/51-6-5-23/34
On the Temperature Dependence of Intensities of the Combination Frequencies V, + 1~5
and 11 + (V1 + V4) of Gaseous CC14
are given in Fig 1. Fig 1 shows that increase of temperature leads to
a slight Increase of the total intensity, broadening of each component
of the doublet and a fairly strong rise of the absorption maximum
of ~the long-mvelongth component. The curves or Fig 1 show only a
qualitative agreement o f theory with experi m-ent. This is con-
firmed by the data of Fig 2, where curve 1 was obtained experimentally
and curve 2 theoretically. AlthoUg~ curves 1 and 2 of Fig 2 are
similar in appearance, the theoretical curve indicates a stronger
temperature dependence of the total integral absorption than that found
empirically. The authors could notauggest a reason for the difference
between curves 1 aM 2. They did establish, however, that the Increase
Of Lthe partial pressure of C014 vapour with temperature cannot explain
this disagreement. There are 2 figures and 4 Soviet references.

PERIIODICAL: Fizika iverdogo telaq 1960t Vol. 2, No, 7# PP. 1619-1623
TEXT: L, I. Korovin and Yu. A. Firsov suggested the use of data on infra-
red absorptionfor clarifying some.partioulare concerning the valenoy zone
structure of tellurium. Their group-theoretical investigations revealed
that two variants.are relevant for the form of the energy spectrum of the
hole band: one ellipsoid in the center of the Brillouin zone or two el-
lipsoids in the G-direation, A. decision can be made when the form of the
bandt which is established by the type of isoenergetic planes is known.
To determine such a form was the main task confronting the investigations.
In the course of them, the authors examined the edge of characteristic
absorption for two directions of the light veotor and background absorp-
tion. The test pieces ixsed for the purpose were made of tellurium single
crystals, that had'been produced at the Leningradgkiy institut poluprovod-
nikov (Leningrad Institute of Semiconductors)*'Poils were cut in parallel

ment, differently oriented microcrystals formed on the surface of the test
pieoesq so that the reflection coefficients of the latter were practically
the same for both polarizations (E11Cp E10) in the whole spectral range.
The experimentall. error in.the determination of the reflection coefficient
did not exceed 5%o On taking account of all other factors, the total error
was found to be Ak/k n! 15 , In Fig* 1, the transmissivity and reflootivi-

D and D,j (penetrability in the ordinary or in the B110-polarized lightp
respectively, for Specimen 1) exhibit a minimum at X - 11 p. By making use
of these data and results from Ref- 7t the authors calculated the absorp-
tion curves for polarized light; they are shown in Fig* 2. The position
of the absorption edge was then determined from the point of inflection
(Ist line of the table) and by means of the extrapolation of the linear
part of the curve to the point of intersection with the abscissa (2nd line).

region, are discussed next. It appears certain that it is closely
related to the free carriers. That the absorption coefficient in the

of the effective carrier mass on the direction, The'main issue is then

"Boltsmann factort' (Ref.4), the authors consider the effect of
anharmonicity of internal molecular vibrations and the effect of
light emission on the intensity of vibrational bands, Formulae
are derived which give the temperature dependence of the
integrated absorption. The new formulae differ somewhat from the
usual expression. Comparison of the available experimental data

TEXT: The Fermi resonance in absorption spectra of multiatomic molecules

interaction (A. S. Ddvydov, Teoriya pogloshcheniya oveta v moleknlyarnykh
kri.stallakh - Theory of light absorption in molecular crystals - Kiyev,
1951). It has been found that the doublet lines must.be polarized at
right angles to one another. Measurements made in polycrystalline layers
of CCI4 showed that both lines are polarized eqiially. Absorption in the'
region of vibration from plane deformation of the symmetry B 1 with the
complex term of the same symmetry were studied in the case of liquid and
crystalline iodobenzene and chlorobenzene. The intensity ratio of the two
doublet' lines I /I is almost I for M for the liquid benzenes < 0.1,

ABSTRACT:,~-. Thti,purpose of the woric was to meaeuro the dispersion and absorption.of
crystallihe..diphenyl, acetylene in the 0.75 to 17 wy wavelength region, calculate
the oscillator strengths on the, basis of the dispersion and absorption data md -
compare the resultant values. The dispersion curves were obtained by the refflec-
tion procedure, The values of the index of rp-fraction were calculated by means of
'A formula involving the reflection at the cryittal-alr interface and the absorption
coefficient,-which allows of determining the index with an error of 15%. The
frequency dependences-of the index of refraction -and absorption coefficient are
consistent with.classical-ele6tronic.theor,7. The osciUator strengths were cal-
culated on - the basis -of the absorption by means of the usual formula and on the
basis of the. difipersion by means of two formulss lased on the Kramers relations.
The,oscillator i.itrengths computed oil the basis or the absorption and dispersion

adJacent. to the fundanto lal absorption edge, The thickneas d of the layers were dq-'
termined to within 2% by an interfororActric method. The transmittance T was
ed by means of SP-4 apdctrophotometor in the 0*4 to 1*2 Is interval and by means of;;.-
