ABSTRACT: The absorption bands of strongly absorbing crystals
(e.g. stilbene and tolane) are still comparatively
wide at liquid-hydrogen temperatures. Vrhen the absorb-
ing molecules are separated by molecules of a foreign
lattice (e.g. stilbene as an impurity in a dibenzyl
crystal) the absorption bands of the impurity are
sufficiently narrow to be called lines- Crystals with
such impurities usually luminesce. The present paper
deals with absorption and luminescence of stilbene in
Card 1/7 ddibenzyl crystals. The resul-11-s vere obtained using a

The absorption spentra were pho-UoGraphed in polarized

temperature of liquid hydrogen, A hydrogen or a
krypton lamp was used as .-t souroe, and an arc, spectrum
between iron ele,-,trodes was used for calibraUion. The
crystal thicknesses in absorpt-Lon studies were from

content was from about 0.001clo' to 3-1;~~' by we'Lght.
To st-ady lumi-nescent spectra crystalline plates of I mm
thickness were usec'. These spectra were obtained from
the same surface of the crystal onto which the exciting
liGht fell. LLuninescence was excited by means of a

differences. If the three series, which begin at
296?2, 29528 and 29468 cm.71, are separated out- from
the luminescence spectrum, then the frequencies of
intramolecular vibrations of stilbene in tolane are
found to be close to the corresponding frequencies
obtained from the Raman sDectrum and from luminescence
of stilbene in dibenzyl. Stilbene and tolane form
a continuous series of solid solutions (Ref.6), -mince
U'heir lattices are practically identical. Introduction
of stilbene molecules into the lattice sites produces
"defects" which become absorption centres. This
accounts for the spectral peculiarities of t-olane
crystals with stilbene impurity which were described
Card 4/5 above. The authors note that tolane itself does no-'L-.

luminesce, but luminescence occurs only from the
impurity levels. In the absorption and I-Luninescence
spectra of cadmium sulphide (Ref.5) the same pe~-.-ijiqr-
ities are observed as in tolane with stilbene. The
difference between CdS and stilbene-tolane li-es in
the fact that the "defects" in the former are due -to
an excess of sulphur or cadmium, %rhile in the latter
the 11defectus" are stilbene molecules. There are 3
tables, 3 figures and 7 references, of which 6 are
Russian and 1 French.

ABSTRACT.- 15ecauae of doubts about the purity of crystals in Wrlier work
(Refs 2, 3) the author2 re-investigated the spectra of naphthalene
in. order to check the tarigin of electron tranEitions in crystals. The
authoro used samples of naphthalene of various origins and purified by
various methods; chemical, racrystallization from solution, sublimation
and rona meltirg. It was fakind that the intensities of the absorption
lines at 2994:1 and 5105o em-' varied considerably from sample to sample
(the samples -ware monocrystalline, of 1 to 5 mm thickness). If the
method of zone melting is used it is possible to obtain a rod of
naphthalene from which layers of various purity can be cut. Such a rod
'was presented to the authors by V.I. Startsev and Yu.V. Naboykin. It
-was found that the 31060 em-1 linek was virtually absent in sample cut
from the region of the rod with the highest purity. On the other hand
samples of low pirity, also cut from this rod, had a strong polarin44

ABSTI~&CT: The authors investigated the luminescence spectnuji of crystalline
naphthalene lying in the region of fundamental absorption. The
luminescence and absorption spectra ware obtained at 20.4, 77,
200-210, 293 ary] 330-WOK. Medium-dispersion quartz spectrographs
ISP-22 and Hilmer 9-2 were used. For the absorption spectra a
krypton lamp G871D-120 was jsed; luminescence was excited with
2530-2400 1 light from a mercury lamp SIIDSh-3.000. A Glan-Thomson
prism was used as an analyser. Very pare samplas of naphthalene
were obtained by repeated zone purification (,15 runs). Purity of
the sr-L-aples was judgei by the absence of P-methyl naphthalene bands
in the absorDtion spectrum. Fig 1 gives the luminescence spectra of
.naphthalene cqstals at 20.,10K. Fig 1 shows a luminescence band at

PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, v. 25,

TEXT: This is a review on studies made at the Institut fiziki AN USSR
(Institute of Physics of the AS UkrSSR) which covered the following
subjects: a) the simplest aromatic compounds (diphenyl, terphenyl,
quaterphenyl, etc.); b) compounds with benzene nuclei which are bound by
carbon atoms not contained in the ring (dibenzyl, stilbene, etc); compounds
with condensed benzene nuclei (naphthalene, anthracene, phenantrene, etc.);
d) derivatives and deuterosubstitutes of some of these substances. Sub-
stances of the same class of hydrocarbons were uded as impurities. The
studies were made with monocrystals. Following are the most important
results obtained: 1) General properties of the spectra: The absorption
bands of strongly abso_rbing substances (stilbene, tolane. anthracene, etc.)

are relatively broad even at hydrogen temperatures (50-100 cm- 1). On the
other hand, the impurity spectra of such substances consist of very narrow,
weakly polarized bands. One and the same molecule has similar frequencies
in different solvents. 2) Nature of impurity centers. Usually, the impurity
crystals have multiplet-type spectra. The spectra of the solutions of
monosubstitutes of napthalene in naphthalene consist of two equal series of
bands which are mutually shifted by constant quantities 6 Y. The phenomena
predicted by the quantum-mechanical theory of absorption and luminescence
of molecular crystals should be studied experimentally. 3) The role of
defects. In the spectra of several crystals near the longwave edge of
self-absorption, very weak bands of 'Largely varying intensity and position
lie in an interval of sometimes several hundred cm-1. These bands are in
resonance with the shortest-wave bands of the corresponding luminescence
spectra. These characteristic features of spectra are related to defects
in real molecular crystals. 4) Mirror symmetry. The bands in the impurity
absorption and luminescence spectra are almost always surrounded by groups
of satellite bands of different intensity.Thc-sesatellite bands are mirror-
symmetrically arranged with respect to the band of a pure electron transi-
tion. Hence, the satellite bands are assumed to belong to the same type of

discrete impurity centers and to be related to the interaction between
intermolecular transitions and vibrations of the solvent lattice. The fifth
section deals with the polarization of bands in absorption spectra. First,
strongly polarized bands were observed in the absorption spectrum of
stilbene in tolane. With increased impurity concentration, the bands in
their absorption spectra are usually blurred and widened., The problem of
the origin of strongly polarized bands in the absorption spectra of
impurities in organic crystals has as yet not been definitely solved. The
introduction of a second impurilty into a molecular crystal strongly changes
its spectrum considerably. The material discussed in this paper needs

TOPIC TAGS: anthracene, luminescence
ABSTRACT: Although there have been many investigations of the luminescence of
anthracene, the nature of its luminescence is.still obscure. Jt has-been shown
that the luminescence at low temperatures is not due to radiative annihilation of
excitons in the main lattice. On the other hand, it has also recently been shown
that the luminescence spectra of naphthalene and benzene have certain character-.
istics that may be associated-with exciton effects and that-should be exhibited by
other molecular crystAls. The paper 4ives,the results of investigation of the
luminescence of zone refined (40 zone) crystal anthracene in polarized light at
20.4, 77 and 20*& lExcitation was realized by the light from a DRSh-25 er-cury

described. Analysis of the luminescence data in conjunctionvith the literature
data on the absorption spectrum shows that the first bands of both components
partially overlap which indicates that they correspond to pure electronic tran-
sitions from exciton bands in the crystal. This is substantiated.by the tempera-
ture dependence of the intensity and width of these bands. Three-other groups of.
bands were distinguished in the luminescence spe ctrum. at 20.4*K:- one is attri-
buted to an impurity; the second is associated -with transitions in distorted host
molecules located near lattice defects; the third is tentatively attributed to
transitions from the lowest exciton band to a set of ground-state electronic-
vibrational levels. Orig. art. has: 1 figure*

ABSTRACT: The absorption and luminescence spectra of single crystal tolan with stil-
behe molecules enter into the tolan lattice in several waysv forming impurity centers
of different natures. The impurity concentration influences the intensity distribu-
tion in the luminescence spectra of different centers. The sharp difference in the
polarization properties of the bands corresponding to the pure-electronic and electro
vibrational transitions in one and the same impurity center is qualitatively explaine
by means of a theory which takes into account the delocalization of the excitations o
the impurity molecules. (Translation of abstract].

ABSTRACT: Results are reported of an experimental investigation of

tolane used was prepared by zone melting to increase its purity.

limation. Luminescence was excited by a mercury lamp and the

spectral sections were separated either with a monochromator or
with a glass filter. A Glan-Thomson prism was used as a polarized-
light analyzer, and most of the0measurements were made with a DFC-13
spectrograph with resolution 4 A/mm. The possible arrangement of
the stilbene molecules, which formed various types of impurity
centers in the tolane lattice, is analyzed in the approximation of
the oriented-gas model. it is shown that the concentration changes
in the luminescence spectra can be related to the occurrence of an
interaction between the impurity centers of different types as the
impurity concentration is increased. The polarization properties
of the absorption and luminescence spectra of the investigated
sYstem are found to differ greatly, and contain bands that can be
set in correspondence with combinations of a purely electronic
transition in the stilbene molecule and the vibration frequencies,
of the tolane. Orig. art. has: 4 figures and 2 tables.

ABSTRACT: The authors have experimental determined the energy and frequency para-
meters of single pulses of a ruby la~elwdith passive Q-spoiler based on a krypto-
cyanine solution. The solution was kept in a cell with optically finished surfaces
andplaced in the resonator close to the mirror with 99.5% reflectivity (Fig. 1).
To prevent generation in the secondary resonator made up by the cell and the exit-
mirror, the cell was inclined to the resonator axis. The ruby used was 120 nm long
and 13 mm in diameter, with matte surface. The energy was measured by a calorimeter
method, and the system used to record the single pulses ensured a time resolution up
to 4 nsec. The output reflector was a Fabry-Perot etalon with two plane-parallel
quartz plates. Its-eneray reflection coefficieht was an oscillating function of the
wavelength and its maximum value was -55%. Such a resonator yielded a single pulse
with peak power -30 M and width -30 nsec. A study of the oscillograms of the single
pulses for different values of initial absorptinn showed that a considerable decrease
+,ekes place in the duration of -the generated pulse with increasing initial absorption.

This result, together with data on the single-pulse energies and the peak power, are
in good agreement with the theoretical calculations of A. Szabo and R& A. Stein (J.
Appl. rhys. v. 36, .1562., 1965). The modulation efficiency, defined as the single-
pulse energy to the laser energy in.the absence of the qrspoiler, decreases with in-
creasing initial absorption_. but this efficiency is still relatively high (33-60%).
This is taken to demonstrate the advantages of q-switching with kryptocyanine. Or'

ABSTRACT: The luminescence and absorption spectra of crystalline
benzene viere investigated at 20.4 and 4.2K. T'ae temperature relation-!
evaluated. Preliminary info ;I
ships in luminescence spectra were rmation
on the structure of benzene exciton zones, includingr their wid'uh and
ef'fective-mass characteristics, were obtained on the basis of a
qualitative analysis of the shape of bands corresponding to transitions_
from the exciton zones to the basic vibration level. [Translation of

ABSTRACT:u Toxoplasmosis has been identified as one of the most common
causes of endogenous eye diseases and the cause of 36% of
all cases of uveitis. The congenital form of this parasitism
is transmitted by women carriers (with no symptoms) to their
children. In 30% of these cases a relapse of inflammation
occurs (in either the diseased or healthy eye) in the form A
of uveitis, chorioretinitis or neuroretinitis. Treatment with
Chloridin and Sulfadimezine reduces inflammation and lowers
the titer of specific antibodies in the blood. The frequent
localization of this disease in the eye is explained by the
lower titer of specific antibodies in aqueous humor as com-
pared with blood serum. Toxoplasmin can be usedjor diagnosis
