ABSTRACT: At first, reference is made to previous papers dealing
with the same subject. The author here investigates the
processes of thermal relaxation of systems with several
equivalent spins 1/2 within an external magnetic field

(which is caused by the interaction of the nuclear spins
of a molecule). Let this field be directed along the z-axis.
The dipole-dipole interaction of the nuclear magnetic
moments, which effects the connection between the spin
system and the thermal motion of the molecules, is relatively
weak, compared with the interaction of the spin system with
the dxternal field. Therefore, these dipole-clipole inter-

TEXT: In the present publication, the author deals with nuclear magnetic
resonance and the structure of matter. The present study was undertaken
with a view to obtaining a clear picture of the physical fundamentals of
the method of nuclear magnetic resonance and to give an idea of its
application for investigating the structure of matter. The mechanism of
nuclear magnetic resonance is illustrated by a scheme (Fig. 1). Some of
the main fields of application of the nmr-method are listed, i.e.,
determination of the gyromagnetic ratio y of the nucleus and the measure-
ment of the chemical shift. The investigation of chemical shift, similarly
to spectroscopic analysis, can be used for detecting molecules and atomic
groups in a sample and determining their concentrations, the nmr method
can also be applied for investigating the structure of isomers. Apart from
Card 1/4

chemical shift, there may also occur a line splitting in nmr spectra,
which is caused by the interaction of the magnetic moments of differently
composed nuclei in a molecule. Spectra showing such line splitting and
an extensive bibliography on qu6stions concerning nuclear magnetic
resonance are given in Refs. 10-12. The chemical exchange of protons is
described in Ref. 13. Soon after its development, the nmr method was
applied for the investigation of polymers (Refs, 14-18). Owing to the
high viscosity of polymer melts, nmr spectra and chemical shift can only
be studied in solutions (Refs. 19,20). A new method of double nuclear
magnetic resonance was developed recently. This method was applied for the
investigation of samples which were not diamagnetic. The principle of the
double nuclear magnetic resonance method is to apply an alternating
magnetic field to the sample while examining the electron resonance line.
The frequency of this alternating magnetic field corresponds to the
Larmor frequency. Interaction of the magnetic moments of nuclei and
electrons leads to a modification of the electron resonance signal, which
can be determined experimentally. By varying the frequency of the
alternating magnetic field, in the proximity of the Larmor frequency ranged

the nuclbar resonance frequenoies'can be determined from the paramagnetic
electron resonance spectra. Since'the above-mentioned effect is caused
by the interaction of the magnetic rAoments of nuicei and electrons,
conclusions concerning the mode'oflelect-ron motion in the sample can be
drawn. Such investigations permit 'an exact determination of the electron
density in paramagnetic crystals. There are 3 figures and 21 references:

pp. 1057 - 1059
TEXTs In the introduction, the author discusses the results of investi-
gation in non-Soviet papers (Refs. 1-6) on the shape of nuclear magnetic
resonance. In the investigation carried out here, the author restricts
himself to magnetically weak substances, i.e., he assumes that the inter-
action of nuclear pairs with the remaining paramagnetic particles may be
neglected, and that the time T 1 of the spin-lattice relaxation is
sufficiently long. The diagram of Fig. 1 shows that the nuclei 1 and 2
move along a circular orbit in a plane whose perpendicular forms an angle
a with the constant magnetic field H 0. The Hamiltonian (1)
z = 9m - tr R 0(S zi +Sz2 W is written down for this system. In this

Hamiltonian, T - describes the collective motion of the two nuclei,
the second term represents the interaction of the magnet 'ic moment
a of the
nuclei with the field H 0 , where r is the gyromagnetic ratio. W is the
secular part of the dipole-dipole interaction of the two nuclei. Further,
the author studies the effect of the tunneling of the nuclei from state I
into state II on the spectrum of nuclear magnetic resonE.nce. More ver, he
assumes that the spectrum of'X consists of two adjacent. levels E and E0

where T' = E1 - E2. In studying the secular equation of (1), the author
restricts himself to a spin 1/2, and assumes that the magnetic dipole-
dipole interaction of the two nuclei is much weaker than the interaction
of their magnetic moments with the constant magnetic field. Under these
assumptions, the secular equation of the 8th order breaks into four
secular equations of the 2nd order, from which the eigenvalues of the
energy E n and the eigenfunctions Tn of the system can be easily deter-
mined. The equation (3) V c(n)X + C(n holds for the

the calculation of the matrix elements of the secular ecuation it is
shown that the spectrum of the nuclear magnetic resonances, under the
above conditions, consists of eight lines whose frequenoies may be
calculated according to formula (7). Further, the author obtains from (7)
a formula for the relative intensities of the lines. The formulas
obtained here do not show the temperature dependence of the spectrum; the
latter must be determined from the temperature dependence of the para-
meters. The author thanks Professor N. D~ Sokolov and Ye. Ye. Nikitin for

TEXT: The authors give a detailed analysis of the e.p.r. spectraof atomic'
hydrogen, methyl, ethyl and polymer radicals adsorbed on several types of
silica gels (specific surfaces 290, 300, and 700 M 2/g). The studies were
made in order to obtain information on the nature and the geometry of
binding and the motions in thes1sorbed state. The e.p.r. spectra were
taken at A - 3.2 cm and a hf-modulation frequency of I Me. The epa spec-
trum of adsorbed hydrogen is characterized by a hyperfLne splitting constmi
of A - 1411�0-1 Me (for free hydrogen it is Ao - 1420.i10 Me and a great

The e.p.r.-spectrum of the ethyl radical consists of 12 lines and can be
considered as quadrupl6t arising on hyperfine interaction of the unpaired
electron with the protons of the CH, group# each quadruplet line being
split into a triplet due to interaction with the CH protons. The e.p.r.

spectrum of the polymer radical consists of six broad poorly resolved oom-,
ponents ( -25 oe distance). The results show that the e.p.r. speotra of ad*
sorbed radicals differ considerably from those of free radicals or of radi-I
cals stabil--zed in solid polycrystalline matrices. The ourface effect be-..,.
comes apparent in a reduction of the hyperfine splitting'constant (for hydiv.-
gen in a deformation of its electron shell).and in a charige of the character
of motion due to losses of degrees of freedom or of equilibrium positions
of the radicals in the matrices. There are 9 figures and. 1 table.

ABSTRAM. The pre-Cambrian Krivoi Rog series (called also Saksagan series,)
is divided into three layers; the middle consists alternatively
of rocks rich and poor in iron (ore- and s-,hist horizons.). Accor=
ding to the changes of the content of minerals in the course of
metamorphosis three groups of rocks can be distinguished:
A. Rich in aluminum and comparatively poor in iron.
B. Rich in aluminum and iron; with two subgroups!
1) Chlorite- and quartzchlorite slate.
2) Ilapetite-chlorite- and magnetite.-stilpnomelane slate.
C. Rich in iron and very poor in aluminum.
The mineral content is given for each group -and their formation

The changes in the chemical composition are shown in a diagram
which contains 75 analyses, the abscissa is formed by the atomic
percents of the most important components, the ordinate by the
value of Fe:M+ + Fe 3+ of the analysis in question. The reaction
of the individual chemical elements in the course of metamorphosis
is discussed; here it can be distinguished between:
1) Elements the content of which is not changed to a considerable
extent in the case of progressive metamorphosis, iron.
2) Elements the content of which changes in the course of the pro=
cess, an increase in the one rock corresponds, however, to a de=
crease in another. silicon, aluminum, magnesium.
3) Elements the content of which only in- or decreases. sodium,
potassium, CO2. --
Rearrangements to this extent can occur only by the transport of
solutions. In the course of metamorphosis there was almost equili=
brium between rock and solutions. During metamorphosis solutions
various also according to their composition are bound to have been
formed in the rocks of various composition.

ABSTRACT: D.S. Korzhinskiy is of the opinion that the usual formula for
the phase rule (n = k + 2 -- r) does not reflect all Droperties
of open systems with completely free varlable components,. He
therefore introduces to the i)hase rule not only such intensive
parameters as pressure, temperature, cheraical potential, but
also extensive parameters such as internal energy, entropy,
volume, and mass. The opinion of D,S~ Korzhinskiy 1.s given (Refl),

ABSTRACTs The basis of this paper is an analysis diagram in which more
than 80 analyses are summarized (Fig 3). The diagram was
constructed in such a way that the gram-atomic percentage
of Si, Al, Fe3+, Fe2+, Mg, Ca, Na, K, C (from the carbonates)
were plotted versus the sum of the gram-atomic percentage of
3+ 2+

the same source.An interstitial solution of the metamorphic
rocks is assumed which had different composition according
to its origin from either mica schists or from rocks rich
in iron. The metasomatosis took place at increasing temper-
ature and on regressive metamorphism. From mica schists
albitites and chlorite-muscovite-alb-ite-schist were formed,
from quart z-magnetit e-amphibole schists magnetite-alkali
amphibole schist, from amphibole-magnetite-quartzites magne-
tite-alkali-amphibole-aegirine rocks, and aegirinites. In
zones of intense impregnation alkali amphibole-magnetite
ores resulted from quartzites containing iron. The alkali
metasomatosis can be characterized as follows: Sodium is
precipitated, silicium is removed, Al, Fe and Mg usually
remain inert, iron is oxidized on the formation of aegirine
and alkali amphiboles, to a lesser degree on formation of
martite. The investigation was carried out under direction
of A. 1. Tugarinov. The author expresses his gratitude to
