Redox Potentials of Dithiophosphates SOV/"6-33-8-.27/39
pentasulphide (Ref 9). For the determination of the (HP) of
the dithiaphosphates (DP), two methods were used - a determina-
tion of the equilibrium constant of the oxidation reaction
of the (DF) with iodine, and a measurement of the (RP) by
the compensation method, The results furnished by the former
method for an initial concentration of the (DP) of
1.85-10"' 3 g.molll are given (Table 1); as well as those obtain-
ed by the potentiometrical measurements of various (DP)
(Table 2). In order to determine the accuracy of determination,
the standard potential was calculated by, means of an equation
(4) for dihaxyldithiophosp4ate and comparedL.vith the experimen-
tal data (Table 3). The reversibility of the oxidation process
of the (DP) with iodine was found@ and-the standard-(R?) of
alkyldithiophosphates was determined for systems in which
liquid disulphide was regarded as standard state. The effect
of the length of the hydrocarbon chain of the (DP) radicals
upon the magnitude of the (RP) was examined, and an appropriate
equation given for calculating the (RP) as a function of
the carbon number of the radicalu The influence of the iso-
structure of the apolar group of the (DPI upon the magnitude

ABSTRACT: In previous experiments, one of the authors, using a special
Ielectronic assemblys observed an artificially retarded process of
pattern recognition. Based on this observation, a description of the
characteristic peculiarities of two approaches to recognition was
given:- The use of one yields a small number of errors but is charac-
terized by the retardation- of the rec6gnition process; the use of the
second is characterized by more rapid recognition but a higher number.
of errors. After analyzing the experimental data, it was proposed
that under certain reception conditions, the speed of recognition pre-
vailed with no substantial loss of accuracy.
The verification of this observation was one of the purposes of
jhe present investigations. Another aim was to reveal the nature of

connection between recognitior@ and the similarity of certain patterns.
Simple, contour patterns were used. The contour was broken down
into portions of equal length. By erasing various portions, lined
patterns containing various amounts of information were derived. The
position of the lines was arranged using a table of random numbers.
The patterns were arranged in three groups according to the a-i-nount
of information. The pattern presentation proceeded from a to a
'large amount of information. The order of presentatidn - within groups
was random and uniform for all subjects.
Two series of experiments were conducted. First, tests for re-
cognition of graphic patterns were conducted. Here . the two methods
of recognition were revealed aInd it was demonstrated -that the second
method had the advantage of higher speed and quantity-of test objects
to be recognized for the majorityof patterns in a given class.
To solve the problem of the link between recogi)ition and
similarity, a second series of experiments was conducted in which the'
similarity, of a pattern to its standard was measured. It was -necessary

t.'.orn had to be more similar than the preceding to its standard. A
1111.1115or was assigned to each pattern. The distribution of numbers
assigned to a given pattern by various subjects was constructed and the
mathematical prediction and dispersion of distributions was calculated.
Later, the mathematical prediction was used to evaluate the degree of
pattern similarity with its standard. After processing these results,
it was possible to isolate 9 of 20 patterns in each series which signifi-
cantly differed from tile standard.
Ex-perimental verification of these patterns according to the same
scheme used in a preceding test showed that of ten subjects, eight - -
assigned a given pattern the same number and that the distribution of
pattern numbers in the abridged and un.abridged,.series was identical!

TITLE: Investigation of GaAs p-n junctions operating as converters of ultrasonic

ABSTRACT: The authors investigated the performance of GaAs diodes to determine the
effect of the gegmetric dimensions of the base on the efficiency of such a diode as
" lu'ttansducer. This influence can be investigated by vaxying In definite
an ultrasoh c
fashion the relation between the thickness of the base and the wavelength of the ap-
plied ultrasonic oscillations, and observing the frequency dependence of the conver-
sion efficiency. The measurements were made at frequencies for which the wavelength
was approximately equal to the base thickness. The diodes were prepared by diffusion
of zinc in n-type GaAs plates and tested by applying rectangular ultrasonic pulses to
the investigated diode through an ultrasonic delay line (Fig. 1). The output-signal
voltage was found to exhibit a definite dependence on the frequency of the ultrasonic
oscillations. The transformed signal had a maximum when the thickness d of the diode

base region was connected vith the vavelength X by the relation d i(2n + 1)/4
(n - 0, 1.9 2.* ... ). In the experiments d was equal to 1.7 x 10-3' cm.- making it poa-
sible to observe in the 7-14 Mcs range up to six frequencies corresponding to the
maximum of the converted signal. This relation is similar to that of a compound
vibrator., and it is shovn on the basis of several other properties that the model of
the compound vibrator can be used for the analysis of the performance of an electro-
acoustic diode transducer. The conversion efficiency depends on the choice of the
geometrical dimensions of the diode. Orig. art. has: 2 figures and 5 formulas.

"Approximate Method of Calculating the Fluctuation
Wequency of Complex Molecules," B. I. Stepanov, 6 pp
'lz.Ak,Nauk, Ser. Fiz!, Vol zi, No 4
On the basis of the method developed by Ellyashevich
and Stepanov for calculating the fluctuation frequency
of molecules, the author evolves a method of approxi-
mating the fluctuation frequency of complex molecules.
The basic inethod was developed.for molecules of the
first matrix. If this same method were applied to
molecules from a 50-stage compound, however, one would
at..
have to conduct socke 250,000- -operationa.-Submitted -

Abstract On the basis of the model of unidimen ional, classical harmonic oscillator
for a complex molecule of group 1, an expression has been derived for the
probability of transitions from different oscillation levels of lower islec-
tronic state to different oscillation levels of upper electronic state.
In the derivation there is taken into account the change in coordinate and
impulse in the process of electronic oscillation transition. Investilption
of the derived formula in the case of invariable impase is effected by nu-
merical integration. It is shown that probability of the transitions de-
pend on transition frequency and also on oscillation energy supply of the
initial level. Elucidated are the reasons of slight dependence of absorp-

ABSTRACT: V. L. Levshin (Zh. Fiz. Khimii, Vol.2, p.641, 1931)
discovered mirror symmetry between the absorption and
luminescence bands of complex molecules. Study of this
symmetry yields information on the vibrational excited and
ground levels as well as on the electronic transitions.
D. I. Blokhintsev (Zh. EkBper. Teor. Fiz., Vol.9, p.459,1939)
showed that this symmetry can be studied correctly only when
X/Va (X = the absorption coef f icient , -4 = -the absorption
freqaency),.and Wtl-4i (W = the luminescgnt radiated power,
Jt = the luminescence Trequency) are plotted as ordinates
against frequency. The authors apply Blokhintsev's analysis
to a series of phthalimide vapours and solutions. They show,

symmetry on the frequency,scale to the absorption and
luminescent bands of 3-aminophthalimide and 3-methylamino-
phthalimide which do not possess such symmetry. These and
other errors of Neporent and Klochkov are due to the use of 4
X and Wt /-Jj as ordinates instead of %/Ia and W04
as suggested by Blokhintsev. The authors show that the
division of molecules into two groups(as suggested by various
workers), one with mirror symmetry on the frequency scale and
the other with mirror symmetry on the wavelength scale, is
quite unnecessary and unsupported by experimental data.
The authors also derive relationships between the absorption
and luminescent spectra in a form of a ratio WLIX , and
between the luminescent and thermal radiated povMrs. These
relationships are valid for condensed systems only.

luminescence (Fig.1) consists of a source of light
a, sample holder b and receivers of radiation v
and g. If the source temperature T. is higher than
@the sample temperature Tbj, then the energy in the
positive direction (from the source to the sample)
Wab exceeds the energy flowing in the opposite direction.

incident radiation power. It is often assumed that
Wba is negligible: this is not always true. The

radiation from the source, the receiver and the sample
holder on results of spectrophotometric measurements.
The author deals In detail with the particular case when
the source temperature Ta is smaller than the sample
temperature Tb, i.e. the case of "negative excitation".'
Negative luminescence, negative Rayleigh scattering and
negative Ranan scattering are discussed. The essential
difference between positive and negat:Lvo excitations, 114a
in the fact that the positive radiationoinay be arbitraqvily
intense. The negative radiation has a maximum value equal
to Uoc/4 r, where Uo = equilibrium radiation density.
Negative excitation Is sometimes more useful than a
positive one. This is so when, e.g., the sample Is at
a temperature of 60000GY since there are no sources of
light powerful enough to achieve positive excitation.
From studies using negative excitation one can obtain
the usual,results: distribution of bands or lines in a
spectrum, relative intensities, polarization, excited-

ABSTRACT; This issue is devoted to the l7t conference on theispectroscopy
of light-dispersing media which was convened in Yoscowton March
29-3o, 1956, on the initiative of the Commission for Spectroscopy
of AN USSR. This conference was attended by representatives of a
series of scientific organisations from Moscow., Minsk, and Lenin-
grad. The introduction gives a summarizing survey on the problems
of the spectroscopy of dispersing media, which is a newly disco-
vered line of spectroscopy. In most cases they just collect and
systematize the experimental material. for the time being. One of
the fundamental problems of this branchof spectroscopy is the
determination of the spectral relations and of the numerical values
of absorption-coefficients and indice of refraction of dispersed
s-ubstances. In dispersed media the variation of the spectrum can
be correlated with a change of the rules of light-diffuaion. Both

tion of the connecting medium, the relative content of absorbed
substance and connecting medium, as well as of the thickness of
the layer. By-varying one of these parameters, or all of them to=
gether, the spectra and the absolute values of the coefficients
of reflection and transparency can be substantially varied and the
dye of the substance can be changed, Many important problems ar, -se
with the study of the luminescence of the powdery materia1z.. No'..
only the re-absorption, but also the secundary luminescence should
be taken into account in this cases The elaboration of these pro-
blems is only in the beginning. The phenomena occuring during the
work with dispersion-light-filters are also within the field of
this branch of spectroscopy. Their theory is almost not elaborated
at present.

ABSTRACT: First are shown the fundamental tasks of the spectroscopy of dis=
persing objects. 1) Determination of the inner properties of the
substance according to the transparency- and reflection spectra,
J. e. determination of the coefficient of absorption of the same
substance in none dispersed state. The refraction-index must be
determined parallel with this. The true spectrum. of luminescence
must be determined with luminescating objects. 2) Calculation
of the coefficients of both transparency and reflection, as well
as of the intensity of luminescence of the whole layer for various
wave lengths if the coefficients of absorption and the index of
refraction of the element and of the connecting medium, the degree
of dispersion, the thickness of the layer and the fundamental
characteristics of luminescence are known. 3) Determination of
the optic properties of the layer of the dispersed substance of
