When measuring the paramagnetic r , anthracite due to electrons for
esynance in
the first time, the authors found n 11 - 0,7 0(.' for the half width of the
corresponding absorptJcn line. Thus, it is considerably less than in other
kinds of minerai coals' A.A. MANENKOV found z2iH = 0,3 Oe in his disserta-
tion Apparently half width differs in different sorts of anthracite. The
last measuring result5 obtained by the authors from samples of anthracite
taken from the KUNECK basin at frequencies of 12,25 and 22 kc were

For the determination of the spin lattice relaxation T the degree of

TITLE: Free radicals during coking of the Angrensk coals.
(Svobodnyye radikaly pri spekanii Angrenskikh ugley).
PERIODICAL:"Khimiya i Tekhnologiya Topliva i Niasel" (Chemistry and
Technology of Fuels and Lubricants), 1757, No.2,
pp. 29-32 (U.S.S.R.)
ABSTRACT: The nature of bindi%-- forces appearing durinE coking
of coal was investigated on an example of ag-lomeration
of the Angrensk brown coal ground to 1-0 mm. The
coal does not cake on heating, while briquettes made
from thio coal (pressed at 2000 kg/sq.cm), heated to
900-1000 C produced coke similar in PrODerties to one
produced from a coking coal. Caking of a coking coal
is often explained by its ability to pass into the
plastic state on heating, but brown coals do not pass
through this stage. The other explanation offered is
an interaction of free radicals in the final stage of
the coking process. It was expected by one of the
authors that the interaction of free radicals during
thermal treatment of non-caking coal fines and
briquettes made from these fines should be different.
Thus, paramagnetic resonance of thermally treated
powdered Angrensk coal should be presont as the coal
particles do not react with each other, while in a

similarly treated briquette it should disappear. To
confirm this supposition measurements of paramagnetic
resonance of the initial coal and that heated to 350,
550, 700, 750 and 900 C as well as similarly treated
briquettes were carried out. Experimental results are
given in Tables 2 and 3. Details of the experimental
procedure are given. On heating powdered coal an
increase in-the paramagaetic resonance was observed, it
attained maximum at 550 - On further heating it
decEeased and became unobservable after treatment at
950 - Samples which after an appropriate treatment were
kept for four days in air, showea a-much higher para-
magnetic effect, the intensity of which was increasing
with the temperature to which samples were hegted (the
width of the peak of the sample heated to 950 C was
twice larger then that of the starting coal). quite
different results were obtained for briquetted coal.
The paramagnetic effect disappeared after heating to
700 to 750 C and was not restored after four days. It
is concluded that in powdered coal there were no
suitable conditions under which an interaction of free
radicals could take place, as individual particles were
not brought closer eiLher by pressing or by the presence

of plastic layer. In briquettes on the other hand, free
radicals interacted during heating and this is confirmed
by the disappearance of the paramagnetic effect. There

ABSTRACT: The dependence of the width of paramagnetic resonance lines
on the temperature in electrolytic solutions was investigat-
ed. Most measurements were carried out at a frequency of the
oscillating magnetic field equal to 1 27 x 1o7 cycles in
water solutions of Mn2+,Cr3+, Cu2+ an; V02+ by applying the
Zavoyakiy method of network current with magnetic field
modulation.
Among the solutions studied, the aqueous solutions of 14n2+_
salts show the arroweet lines. A number of experiments dis-
covered that Mn +-solutions produce 6 peaks of hyperfine
structure at high frequencies, and at low frequencies a
_QUEW_-~' single peak with a g-factor approximating unity.

The temperature-dependence of the line width for MnC12 aqueous
solutions of various concentrations is represented by the
curves in Fig. 1 in the article. It can be seen that all
the our9so have minima corresponding to the same temperature
ofrV80 0.
The temperature-dependence of the line width for some other
solutions is represented by Fig. 21 which shows that the
slope of the lines decreases with a decrease of concentration.
The temperature-dependenot of the line width for the mono-
molecular aqueous solution of Cu(N03)2, represented by Fig. 31
shows that ths line width increases proportionally to the
square of the temperature.

PLRIODICAL Doklady Akademii Nauk SSSR, 1957, Vol 113, Nr 6,pp 120-1243 (U.S.S.R.)
ABSTRACT The authors of the paper under review conducted measurements of the paramagne-
tic resonance in a congealed vitreous solution of borax, this solution contai-
ned iron.The cylindrical samples were obtained by melting together 5 mg of
FeCl3.6H&O and 4 g of borax.Samplef I contained an iron which had been enri-
ched with the:botope Fe5T up to a concentration of 71-910/o,whereas the ana-
logous sample t Il contained the common mixture of isotopes that had not beou
enrichad.The measurements were conducted at 770 K at the frequencies of 1150
24o and 430 magacycles,and they were carried out with the aid of the method
of the grid currentpwith the constant magnetic field H being modulated.
The amount of the effective g-factor,the asymmetrical shape of the curvea)GII
(H),and the widening of these curves at frequency multiplication (all these
phenomena can be observed in sample # II) permit to draw the following con-
clusioniThe ion Fel++ is under con&ions that are analogous to the conditions
in the derivatives of haemoglobin.It is probable that also in the case con-
sidered in the paper under review the lowest Kramers doublet (Us a + 1/2)
is in a considerable distance from the other sublevels.In such a cage,taking
into account the law frequencies employed in this inveatigationjone has to
expect that the maximum of the absorption corresponds to the effective g-fac-

ried out with the sample J~ II. For the enriched sample t I) the curves k
(H) are at all three frequencies much'wider than the corresponding curves for
the sample t II. In sanplefl, there can be observed next to the main ma-
ximum of absorption a poorly resolved additional maximum which is located
at lower field intensities than the main maximum. The maximum of the sample
;# II lies between these two maxima.
These results can be explained by a nuclear spin I a 1/2 of the botope Fe57.
The constant of the hyperfine structure amounts to approximately lo gauss
and is slightly anisotropic. This value by several times larger than the va-
lues obtained in earlier investigations. Such increase of the constant of
the hyperfine structure is possibld because the large initial splitting
must be caused by an admixture of excited atates,partioularly of the state
3049.

here. In cane of absent; oxy67",n only a very weak decreaoe
of A H on occasion of a heatiriE: of the sample from 77 to
3950K is observed. In case of a sample which is in contact
with air the curve &H is higher, whereon in the temperature
interval from -300 to -2500K a sharp increase o" the line
width is observed. The experiments with the same sample
are well reproducible. The variovj samples cave somewhat
different results at an air preasure of 760 torr. An
especially strong change of the absorption line is ob3erved,,
when the finely pulverized sample is in direct contact with
the liquid oxygen. But on occasion of contact with liquid
nitroGen the dependence A 11 (T) remains about the same
as in case of the evacuated specimen. The here discussed
experiments show that the change of the half-width is caused
completely by the oxygerymolecules which are ab3orbed on the
surface of the aa-diphcnyl-p-picrylhydracyl, A widening of
the line also was observed in an NO 2- atK,.osphere. In

gases considerably shorten the period T 2, which determines
the line width. The most important factor thereby is the
strong chaaige of the line width near 2750K, probably
bedause of a change of the character of the motion of the
02-molecules on the surface of the aa-diphenyl-P-picryl-
hydrazyl. At tetiperatures above 2750K the adsorbed oxyt:en
has a high free motion on the surface of the sample,
,whereas at temperatures below -2750K the notion of th~.

.surface of aa-diplionyl-p-picrylhydracyl is the first stage
of the oxydation of this free radical, but the oxydation it-
self takes place slowly.

ABSTRACT: The data given by various authors on the width of the line
of the paramagnetic resonance of the compound (DPhPII)
mentioned in the title I vary con3iderably: from v 1 to "6 OaTtel.
In order to explain this fact, the first author suggested to
deal with the subject mentioned in the title. DPhPH was
produced according to the method described in reference 3
which differs from the Goldschmidt method (Ref 4). The solvents
used were; benzene, toluene, xylene (isomeric mixture),
pyridene, bromoform, carbon tetrachloride, chloroform and
carbon disulfide. For the method of measuring the resonance
see reference 5. The values of the width of the lines of the
paramagnetic absorption (A H),/, mentioned in the title, show

hydrazyl Obtained From Different Solvents
that the nature of the solvent has a considerable influence
on the width of the line. Naturally this leads to the
conclusion that the molecules of the solvent form part of the
crystalline lattice of t'he DPhPli (Refs 6-9). In no ca,e
however, there is a guarantee that the experimenter dealt
with chemically pure compounds. The data of table 1 show that
the solvents used here, are dividerl into two groups, according
to their influence on the width of the line: a. compounds of
the cyclic type, b. compoiinds containing no cycles. In
DPhPH specimens of the group a. a narrowing of the absorption
line takes place, in connequence of cooling and of an increase
of their frequency. Group b. in such cases shows a widening
of this line. On the whole it may be said that the specimens
of group a. des-pite of their broader lines, are more
magnetically isotropic than the specimens of group b. All this
has to be considered as something more or less provisional.
The observed dependences'can only be explained after further
investigation. Furthermore both DPhP11 groups show a different
influence of the atmospheric oxygen on the breadth of line.
On the whole widening of the line by means of 02 is reversible.

Finally experiments of the authors are described in which
one solvent (chloroform) was replaced by another (benzene).
The crystals developed by chloroform, showed wider lines after
they had been recrystallized with benzene. With a reverse
sequence of the solvents used, the crystals maintained the
line of a benzene specimen. Thus it seems that the affinity
of benzene and DPhPH is stronger than that of chloroform. If
DPhPH is used as a standard for defining the number of
paramagnetic centres In different substances, it has to be
done very carefully. Only a DPhFH preparation from a certain
solvent may be used. In the case of a DPhPH synthesis from
other solvents, the exact details of the experiment have to
be given, or the experimenter will get various results.

ABSTRACT: Microwave spectra were recorded of solutions of acetyl acetonate-,
nitrate-, othanolamine-) and diethanolamino complex salt3 of
Cu(II) with the frequencies of V, - 9392 and V2 - 1569 mega-
cycles (Fig 1). In transition from frequency ') , to frequency
-j~ , the hyperfine structure of the spectrum varies in ac-
cordance with the relaxation theory by H. M. McConnell (Ref 2).
Table I gives the g-factors for the hyperfine structure of the
investigated spectra. The deviation of data from the values
found by B. R. McGarvey (Ref 1) for acetyl acetonate is ex-
plained by the fact that McGarvey produced his solutiona from
solid, waterfree acetyl acetonate, whereas the authors pro-
ceeded from the nitrate Cu(110 3)2'3H20' and their solutions

theoretical expectations. Further, the influence exercised by
the correlation time -to (Rof 2) upon the sh-ape of the spectrum
was investigated. By the addition of diamagnetic ionis (UCI)
additional aleetrical "fxiction" waij pruduced, and a noticeable
increase of npeotrum asymmetry was attained. What has not been
explained is the phenomenort that the aqueous solution of the
ethanolamine complex in a concentration of 1.2 mol/l at a
frequency of 1)1shows one single line, the width of which Is by
30-40% narrower than the full width of the hyperfine structure

COVERAGE. According to the annotation the book is the initial
attempt to present a complete review of investigations in the
field of electron paramagnetic resonance (EPR]. It Is based on
the literature published prior to 1959. The phenomenon of EPR
is said to have been discovered in 1944 by the Soviet physicist
Ye. K. Zavoyskiy. The authors stress its Importance and value
as a method of physical investigation in solid-state physics,

TITLE: 'hide-range spectrometer for nuclear quadrupole resonance
PERIODICALt Akademiya nauk SSSR. Vestnik, no, 1, 1962, 74 - 76
TEXT: Nuclear quadrupole reaonan~~e indicates slightest changes in a
molecular electron cloud. The search for the unknown signal must be con-
ducted in a wide frequency interval. For this purpose, a spectrometer
for frequency ranges from 1 to 60o - 800 Mc/sec, which was designed
jointly by physicists and radio engineers, had to be built. At the
suggestion of the Institut elementoorganicheakikh soyedineniy Akademii
nauk SSSR (Institute of Elemontal Organic Compounds of the Academy of
Sciences USSR) and the Fiziko-tekhnicheskiy institut Kazanskogo filiala
Akademii nauk SSSR (Physicotech.-ical Institute of the Kazan' Branch of
the Academy of Sciences 'USSR), work wan started in 1960 for the purpose of
developing a wide-range quadrupole radiospectrometer, The instrument was
built under the direction of B. N. Pavlov and D. Ya. Shtern. V. I. Robas,
I. A. Safin, K. G. Semin, and. E. I. Fedin were consulted. Samples of the

AKC-1 (YaKS-1) spectrometer were built, which permits investigations in
the range from 1 to 600 Mc/sec., In the supraregenerator for 90 - 400 Mcfiw
and in the detector,the sample can be kept at constant temperature between
-196 and +1200C. A lot of YaKS-1 spectrometers is to be built in 1962.
There are 4 figures.

was found that less electrical conductivity produced mor.e symmetrical-
resonance lines. The following results are valid for symmetrical peaks
and VOCl 2 aqueoua solutions of 0.02 mole/l. The dependence of the width
of the peaks (see reference) on the nuclear spin projection m I is given by

ViSCOSity is reduced. When 6)0 T the ratio a2/a3 is independont of
temperature and viscosity. T c is the characteristic time'-,f the correla-
tion function of the Brownian motion. a 1 depends on temperature to a
lesser extent than a2 and a 3' This indicates that the relaxation mechanism
(differing from the McConnel-mechanism) is predominant in a 1 and conse-
quently also in that part of the half-width of the hyperfine structure
components which is independent of the nuclear spin orientation. The most
ProIUable mechanism is chat suggested by S. A. AlItshuler and K. A. Valiyev

soluble in benzene, chloroform, alcohol, acetonitrile, glacial acetic
acid and dioxane. In dilute solutions (< 10-3 moles/1), the spectra show
a hyperfine structure, the analysis of which proves that the unpaired
electron in I remains mainly on the nitrogen atoms. A comparison of the
o.p.r. spectrum of I with the spectrum of the a,a-diphenyl-p-picryl
hydrazyl radical (DPPH) showed that the additional hyperfine structure is
due solely to the protons of the a-pheny'L groups. It may be explained by
the interaction of the unpaired electron with the 2,4,6-protons of one of
the two a-phenyl groups. The value obtained for the constant a of hyper-
fine coupling was 1-7 oersteds, and for L% 1.1 oersteds. The relative

TEXT: The e. p. r. spectra of some compounds of bivalent silver were
studied in order to confirm experimentally the strong covalent bond between
silver and the ligands which has been postulated by K. Do Bowers (Proc.
Phys. 500. A, 66, 666 (1953)) for ~Ag(py)41 S20,*, and to ascertain the strong
exchange interactions between the 4d-electrons; which are expected in
analogy to Cu II compounds. Results: Fine crystalline Ag(C 5H5N)'j32 08 A)

g: - 2.06+0.01, and with 11 superposed peaks of the hyperfine structu;e.
This specirum is explained by the covalent bond of the Ag (II) ion with the
pyridine molecules containing a nitrogen atom with I - 1. Solid solutions
of A with the isomorphic cadmium compound did not make it possible to
resolve the hyperfine structure, but undercooled solutions of Ag(No 3)2. xH 20

well resolved doublet with gi; a 2-337t 9i - 2.071, contrasting with the
data by J. A. Mcidillan, B. Smaller (Chem. Phys. 35, 1698 (1961)). There
