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 543 Free radicals during coking of the Angrensk coals. (Cont.) 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 Csrd 2/1 543 Free radicals during coking of Ang-rensk coals.

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. 48-6-10/23 TITLE: Electronic Paramagnetic Resonance in Electrolytic Solutions (Elektronnyy paramagnitnyy razonana v raatvorakh elektrolitov) 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.

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.

Further the photographs of several line.,3 are addod 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.

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~. adsorbed molecules freezeq. The adsorption of oxygen on the .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.

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 Paramagnetic Resonance of o~*-Diphenyl-A-picryl-- SIOV120-126-4-21162 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. Paramagnetic Resonance of ct,cl-Diphenyl-Fpicryl- SOV/20-126-4-23/62 hydrazyl Obtained From Different Solvents 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.

TITLE: Paramagnetic Resonance in Solutions of Complex Copper Salts PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 127, Nr 5, PP 1044-1046 (USSR) 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 Card 1/2 therefore contained remaina of cryatal water.

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 spectra of diluted solutions.

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 Card 112 47 510301'~ 000/001/006/011 iiide-range spectrometer for ... B105/B101 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. Card 212 KOZYREV, B.M.; RMBD~ A.I.

It 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 2 a1 + a 2 MI+ a 3mi. The coefficients at a 21 a3 determine the width Card 1/3 5/05 62/042/005/001/050 Slectron paramagnetic resonance in ...

The dependence of 6H on m becomes less sharp when temperature is increased.and consequently 1 2 2 . j 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 t ~Zh'-'T:F, 35o 947, 1958).

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 _C_ ~rd 2/,4 Study of the free radical ...

TITLE: Electron paramagnetic resonance in compounds of bivalent silver PERIODICAL: Akademiya nauk SSSR.. Doklady, v. 147, no. 2, 1962,-365-367 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) showed at 450 Mcps and 770K a peak with g - 2.15, 26 oerst' This, and also the independence of the coefficient of paramagnetic suscepiibili-ty V~jofllal0indicate an exchange interaction between the 4d electrons.

Aqueous solutions of A gave at 77 0K a curve with go - 2.i6o.oi, 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 ,n HNO 3' and Ag(Clo 4)2 in HC10 4 showed at 77 aKj 9320 Maps an anisotropic well resolved doublet with gi; a 2-337t 9i - 2.071, contrasting with the data by J.
