PURPOSE: The book is intended as a text for students of higher tech-
mical schools.
COVERAGE: The author states that theoretical and experimental physics
should be taught separately in higher technical schools and that
the student should take a course in general physics before he on-
gegm in laboratory works This text, therefore, emphasize& the theo-
retical principles of physics and does not require a knowledge of
mathematical integration but only a comprehension of definite inte-
grals. The book differs from other Soviet physics texts in that
the structure and properties of matt*rare treated separately# and

ABSTRACT: The author explains first the concept of dynamic
stereochomistryt ahoaing it In coruiection vilth
the new term of conformation of molcculetr; and con-
formational analysis - the ne;*i not'.od of studying
chemical reactions. This opened a field oaf chenistry
which may be called dynamic atarcoc,".cmistry. He
then outlines the cases in which the static con-fi-
guration becomes inaurficient to explain the chaai-
cal behavior and properties of the molecule, and
when dynamic conformation roplacco the molccule.
lie quotes an example explaining the sense of the
terms and draws the conclusion - when spatial arran-

cule it may be said that it possesses a sinrlo
conformation. If, on the contrary, the heat move-
ment causes the molecule energy to oscillate near

cases of conformational transformations, the author
acquaints the reader with the basic lants of the
geometry and mechanics of raoleculest and the struc-
ture of ordinary molecules in Which chemistry was
faced with conformational problems. -For this pur-
pose the article shows 3 pictures representing mole

hexane, The author then deals with the conformation

ABSTRACT: Conditions for forming solid solutions have beon
formulated in accordance with the work of A.I. Kitaygorad-
skiy Otef 1) and state that for the formation of a con-
tinuous solid solution isomorphism of the molecules in a
necoxaary,but not a sufficient, condition. Two cases
were examined; mixdd symmetrical and asytmetrical molecules
and mixed crystals-, the moleculos of which are symmetrical.
This covers the phonanthrone-anthracene system where both
molecules are symmetrical but have different symmetries.
Theory would predict the Impossibility of a continuous
range of solid kolutions even in the case of great simi-
larity in the forms of the molecules and their packing in
the crystals. Bradley and Marsh (Ref 3) showed by
thermal analysis a continuous range of mixed crystals.

experiments showed the anthracens structure up to 20%
phenanthrene and the phenanthrene structure up to 10%
anthracene but no uniform structure In between. Liquidus
and solidus temi;--Oratures were measured for various
mixtures of the purifiDd components. Except for the
range 20-80% anthracene single crystals were grown -
usually platy in form. The composition ill the mixoj
crystals was found by U/V absorption spac roicopy
Anthracene crystals have the space group C 2h - P2 @C,

Z = 2 . The parameters were found (using an RKU--86
camera) to be: a = 8,5206-, b 6.oolo. c - 11.1377 +

Examination of the hot reflexions in the mixed crystals
with up to 10% anthracene showed the phenanthrene structure
-and correspondingly for up to 20% ph*nanthrene. The
olid solutions were well ordered. For mixed single

indicates tCat the phonanthrone molecules are well
inserted into the space left by the neighbouring anthracone
molecules. To show this, interatomic distances were cal-
culatod from the known structure of anthracens. The
minimum intermolecular distances in tho layers between
II...H atoms in 3,05 kX and between H ... C in 2.8o kX.
The latter is less than the usually assumed distance oC

2.50 kX. As the phenanthrene structure has not been
determined the analysis at the other end of the composition

TITLE: One-dimensional Diffraction in X-ray DiffractionPatterns
from Polymers
PERIODICAL: Krintallografiya, 1959, Vol 4, Mr 4. pp 625-627 (USSR)
ABSTRACT: Theoretical. One-dimanBional diffraction showing an
intensity distribution spread out continuously along
layers in reciprocal space is sometimes encountered for
systems of chainA which are parallel but otherwise
disordered. It is, however, shown here that one-dimensional
scattering can occur when there are only slight departures
from strict three-dimensional order due to defects in the
packing of chains, The effects of distunbances of the
proper inter-chain distances in the equatorial plans and
the displacements of the chains parallel to their axes
is examined. It in assumed (A) that the packing defects
consist of the chance departures of the chain axes from
the positions they 'Would have in the ideal lattice or
W that the defectiveness of the packing increases in a
radial direction. The result for (A) is analogous to that

obtained for isotropic thermal vibrations but there is
a supplementary term causing the intensity to be distri-
buted in layer lines. for the zero layer, the intensity
falls off at large and at small angles and for higher
layers it decreases with distance from the meridian. For
(B) the diffraction field will got narrower but the lines
will become wider than in the first case. If the dis-
turbance to the long-range order increases, then on the
zero layer the scattering will become of the gaseous type
with an increase at low angles. Thus, if such a
disturbance occurs then a continuous intensity distribution
along the layer lines arises, because of the one-
dimensional diffraction of the separate chains.
