'ground state WO; when W,, . W0, no change takes place. With a sufficiently
large difference between W1 and W., a rapture of the hydrogen bOlLd is
possible during absorption and emiseion. As a result, the values of 6)o

of a hydrogen bond, are strongly increased. Although always two bands

TE)".: The conditions for dark conservation of photopolarization in photo-
electret3 consisting of single crystals or polycrystals of S, of polycryntalline
anthracene, of powdery S - CdS mixtures, and of a pressed anthracene - Cds Miz-
ture %.,,ere investigated. The initial depolarization current on illumination of
the nolerized photoelectret was taken as the measure of photopolarization. Me
initial decrease of polarization is slowed down when the polarizing voltag~e is
increased, The drop of photopolarization of the polycrystalline anviracene
clectret pbjected to high pressure is slowed doim when pressure is inc:reased
to 2 t/cm . The degree of photopolarization drops at the same time. Witli
electrets subjected to a pressure > I t/en2, where the density of the photo-
clectret mass does not change any more, the characteristics of conservation and

the decrease of the number of electrons localized in zhallow traps connected with
the surface of individual ar7stalline particles of the electret.

TEXT: A general equation is derived for the depolarization that
occurs in darkness. The assumption is made that the electrons freed
from traps and migrating into the conductive zone reconbine with
stationary holes. The paper investigates the concentratio.a of free
electrons during depolarization in the dark, starting vitt',i a notion
of the mechanism of the processes taking place when the electrodes
are short-circuited. It is assumed that the trapping of electrons
predominates over the recombination of electrons with holes, and
that the concentration of trapped electrons is considerably lower
than the concentration of traps. The results of the calculation per-
mit a graphical determination of the depth of the local trapping

the oxygen analyzed is that which was not consumed in respirati:in. Tts
isotopic composition depends on the ratio of the intensitles of thqse tw.-)

remaining conditions are given in Table3 I and 2. The dat-a obtained
(Table 1) chow that the fractl--:mation coefficient of the oxygen isotopes's

of this coefficient for each type of plant the authors hold the opinion
that the Influence exerted by respiration on the isotopic composirion
( on the example of Seenedeamus and Elodea) can be 4etermined by de-
termining ok under the conditions of photosynthesis. The authors arrive at
the conclusion that the opinion expressed in the beginning concern-,`,ng
the "rendering heavier" or photosynthesis oxygen by respiration to correct,
and they derlve equations (1) and (2) for the isotopic composition of the
oxygen remaining after respiration as well as for the reepixation in-

investigated the topic mentioned with the water weed (Elodea
canadensis) (fresh water), on the one hand, and with phytoplankton
(mainly Diatomaceae algae, sea water), on the other )md. The
photosynthesis took place in water treated with argon free from
oxygen (027content 0.3-1 ml/liter) at sunny Treathor tnd under
optimum conditions. Table I shows the results. The disturbing
offoot of the residual respiration oxygen_. which was hezorier in
consequence of preferred absorption of O-LO, was eliminated as far
as possible by repeated extraction of the oxygen prod-aced by
photosynthesis. The method used for fresh water and tae water weed
had to be 'replaced by that of Winkler for marine planacton sirce
the extraction of oxygen weakened the intensity of tho photosynthesis.
The average value of the isotope content of the phototiynthatic -
oxygen of marine phytoplank-ton (0.2002) (0 is related to 017; the
small content of 0 17 was neglected) in higher only by 0.0009%t
i. e. higher by I.OV~,than that of sea water (mass-speattum
determination in Table 2). This means that 90% of the
photosynthetic oxygen occurs in water. In the case of -the water
Gard 2/3 weed a similar calculation yields 82%. In the experiments with the

the experiments with the water weed and in the experiment Nr 2
with marine phytoplankton resulted from the deviation of the

respiration from the assumed average value. There are 2 tables
and 8 references, 2 of which are Soviet.
