Bul Chi TITLE: Bresestrahlung of Slow Electrons Interacting With Neutral Atoms PERIODICJLL: Zhurnal sk:perimentallnoy i teor*ticheskoy fiziki, 1960, Vol. 39, N . 6(12), pp. 1770-1776 TEM A theoretical study has been made of bremastrahlung arising from the collision of slow elect---one (E e< 3 ev) with neutral atoms. Above allt it is shown that the br*mestrahlung cross section may be represented as a function of the elastic acattering cross section of electrons by atoms. The absorption coefficient of bremestrablung has been calculated as well. In the introduction, the most important formulas are presented, including an expression for the intensity of radiation emitted by the electron-atem system: 2 41 4 1 12 . 4Z206 r 0dir'0 2 S V Qb r.dro Qab 2 3 3 3c' 3m 0 r0 Card 1/4 88458 Dremastrahlung of Slow Electrons Interacting S/056/60/039/006/050/00 With Neutral Atoms B006/BO63 r Q ab (10 (Z+l)f f ?b T adT I ... dT Z ,r0is the radius vector of the inciding electron.

In first approximation, the disturbance of the atom by a slow electron manifests itself in the polarization of the atom. If the period of natural oscillations of the atomic dipole (-10-16 sec) is very small compared to the time of flight of the electron through the atom (Y e< 108cm/sec) thn dipole undergoes an adiabatic C&rd 2/4 88458 Breasstrahlung of Slow Electrons Interacting 3/05Y60/039/006/050/063 With Neutral Atoms B006 B063 I '-* --" --R variation and d - aE - aeir/71, where a im.tbe polarization coefficient, and i~ is the radius vector of the inaident electron in the nuolea--,, system. e. 2. an .. 3 j2 4.

The properties of the reaction products as coatings were compared to those based on phthalic anhydride. The rates of the polycondensation reaction and the energies of activation are graphed and tabulated.! It was found that this polycondensation is a two-stage reaction. The first of these stages is fast, almost independent of temperature, and leads to the formation of the acidic esters. The second stage, h 'ighly temperature dependent, was found to be a sec- ond order reaction.

Oxidative degradation was studied in the 180-:2400C range and at an initial oxy- gen pressure of 200-500 mm lig. The low values of the activation energy of thermal degradation in all polyesters indicate that the process proceeds via a complex mecha- nism. The involvement of the free radical:type inte:rmediates in the thermal degredatic is suggested. The IR spectra indicate that thermal degradation in polyesters involves the cleavage of the C-0 bonds of the eater groups. The IR spectra showed that the UDC. 678.019.3 : [678.67416415221448+ Card i io . +fi7Q_A7U1q99'uUR'ft9n *I L 08ri,99-67 ACC NR.

TITLE: Investigation of the Dibenzene-chrome Derivatives by the Method of Paramagnetic Electron Resonance PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheakaya, 1959, Vol 23, Nr 10, pp 1263 - 1264 (USSR) ABSTROT: In earlier papers (Refs 1-3) it has already been, shown that in highly diluted dibenzene chrome solutions the interao'6ion be- tween the unpaired electron and the protons of the benzene rings,. which are in dixe_,3t connection with the metal (chrome-) atom, manifest themselves by a distinct hyperfine structure of the spectrum of paramagnetic electron resonance. It has already been shown that the introduction of a substituent into the benzene ring influences neither the g-factor of the compound nor the amount of the hyperfine splitting (3-~�O-5 Gs). It was further found that the dissolving temperature, the nature of the solvent or that of the substituent introduced into the benzene ring influen-ries the width of the hyperfine structure component. Further investigations concerned the spin density Card 1/3 distribu',_J:o-i of the unpaired electron in the molecule, the Investigation of the Dibenzene-chrome DerivatJves by SOV/413,;L-3-10-35/39 the Method of Paramagnetic Electron Resonance hyperfine splitting, as well as the width of the hyperfine structure component. In 'his :connection, several details, which were obtained from referenoes 1-8 are briefly discussed. Further investigations concerning hyperfine splitting were carried out with the cation of dibenzene chrome with cyclo- hexyl substituents in both rings. It was found that at low temperatures of the solution of this compound an additional triplet splitting (1+0.5 Ga) of each hyperfine structure com- ponent occurs. It is caused by the interaction of the unpaired electron with two protons of a cyclohexyl substituent. An in- vestigation of the influence exerted by various factors on the width of the hyperfine structure component gave the fol- lowing result: A considerable dilution of the solution with a reduction of temperature loads to a monotonic improvement of the spectral resolving powAr,, i.e. the width of the hyperfine structure component decreaaea. In some solvents (e.g. alcohols) an anomalous temperature dependence of the spectral resolving power is found; this might be explained by a complex formation between the dibenzene chrome aations and the molecules of the Card 2/3 Investigation of the Dibenzene-chrome Derivativ-es by SOV/48~-23-10-35/39 the Method of Paramagnetic Electron Resonance solvent.

The studies were J made with conoenArated solutions (more than 0.02 mol/1) (solvents - ethanol, pyridine, acetone) by means of a spectro- meter with a high-frequency modulation of the magnetic field (Ref 5)- It was observed that at the gradual lowering of temperature the -width of the superfine structural component (A H) of (I~ and (IS) is constantly reduced, and,reaches a minimum at -50, -80 C- When the temperature is lowered beyond that, the width increases again. In all solutions of (1) and * Card 1/2 (11) investigated, two additional lines were observedn They SOV/76-3;-9-37/35 On the Temperature Dependence of the Width of the Component of Superf'-ne Structure in Electron Paramagnetic Resonance Spectra came about by a superfine fission at the Cr53 isotope. It is stated that there exists an anisotropy of the g-factor a.-id a superfine siructure in the chromium--aromatio compoun, Besides the temperature reduction, there are two more re _;one for the extension of the com;onent of superfine structure: One is due to the formation of stable complexes or solvate shells, and the other one is in no connection with the exchange interaction. In order to solve thin problem it will be neces.- sary to carry out studies with diluted solutions in which the latter effect is negligible. It is ascertained -that a temperature reduction may cause a better dissolution of the superfine structure than a dilutiong and if this comes about it can be observed with less sensitive instruments.

The measurement results and the calculated spin densities of the unpaired electron are summarized in table 1. To investi- Lf/ gate the transmission of an electron along the chain of the conjugate or saturated bonds the e.p.r.-spectra of the anions of stilbene, azoxybenzene, and dibenzyl were investigated (Fig 3). In stilbene the possibility of a delocalization of the electron along the benzene ring and along the chain of the conjugate double bonds was proved. The apectrum of azoxybenzene H H 0 showed that the replacement of the bridge -C-C- by -N-N- does not reduce the mobility of the electron over the entire molecule.

This cannot be explained oy the presence of a corresponding quantity of the oxidized form of the forricinium'cation. Table i shows that also polymers in which the.feracens links are separated by the -CH.-CH27 group give an e. p. r'. signal. 1:k is known that the delocalization of the unpairsil electrons between t6 two phenyl rings Is not: Prevented by this group. In the substances described here. which give an a. P. r. signal, this signal is the smaller, the smaller the number of Jerrocene links is. This signal vanishes in 2). Polymers with a low molecular weight give no e. p. r. signal 'in the solution (bonzene), but in solid state. This is explained'by the fact that the intramolecular interactions cause In solid state a conjugation of the adjacent polymer molecules. This causes for its part an 9. p. r. signal.* All polymers Oard Vfk5- 23654 5/020/61/137/006/013/020 Synthesis and some B103/B217 giving this signal show a single symmetrical line of the e. p. r, of the Lcrenz type. The 1) obtained from th-e reaction A yields a wide a. p. r. line of 120-160 oersteds, its width bAng dependent on the polymer atructure. This line becomes broader on reducing the measuring temperature. Its width is changed moat considerably in low-molecular iialymers. The authors believe the nature of the measured signals to be unclarified, they cannot maintain that the number 11 of the unpaired electrons per I member, deter- mined by a comparison with the standard, corresponds to their actual number. N may, however, be a certain characteristic of the magnetic properties of the system. (nou. 2-4); N roaches an anomalous size in the Insoluble tt polymer its. 5.

Vol 8, Nr 1, pp 137-140 (USSR) ABSTRACT; Chromium dibenzene, is a representative of a new type of compounds known as sandwich type compounds. In these compounds the metal atom is not bound to a single carbon atom but to the wholan system of an aromatic hydreearbon (Refs 1, 2). The present paper deals with distribution of the spin density in- the chromium dibenzene cation. The spin density was found from the hyperfine structure (h.f.s.) from electron paramagnetic resonance (&.p.r.-) spectra of strongly diluted solutions of the chromium dibenzene cation and solutions of chromium dibenzene cations with loopropyl and cyclohoxyl substituanto in both benzene rings. Fig 1 shows the e.p.r. spectrum of the chromium dibenzene, cation obtained in an acetone solution at -700C. From the ratio of the h.f.s. intensities and the constancy of the hyperfine splitting (3.6 � 0.5 0e) it follows that the unpaired electron interactswith protons of both benzene rings; all twelve protons in these rinGs act 'in the same way. Voyevodskiy, Molin and Chibrikin (Ref 7) found that Card 1/3 in#-.roduction of a hydrocarbon substituent did not alter the tuagnitUde 68329 SOVI51-8-1-36140 Distribution of Spin Density In the Chromium Dibenrene Cation C,-Nrd 2/3 of the hyperfine splitting &nd that the niuiber of the h.f.s. components represented the number of the remaining protons in both benzene rings. A more detailed Investigation carried out by the present authors showed that in the spectrun of the chromium dicumene cation (Fig 2, at -900G) each component of the ring proton h.f.s is split, into a triplet with a separation close to 1.0 Oe. This additional triplet splitting is due to splitting on both ot-protons of the isopropyl substituants. Similar effects were observed in the case of the chromium dibenzene cation with a cyclohexyl oubstituent in both benzene rings. Bubnov and Chibrikin (Ref 8) reported additional hyperfine splitting in the spactrum of the chromium dibensens cation in solution, which vas ascribed to intoraction of the unpaired electron with a magnetic moment of the Cr53 isotope which is present In the natural chromium. This -was also found by the present authors and is shown in Fig 3; the hyperfina splitting between the h.f.s. components of chromium amounted to 19.0 Oe. All the a.p.r. spectra reported by the authors were recorded with a spectrometer described earlier (Rof 9). McConnell and Chestnut (Ref 11) suggested an indirect interactlon to explain hyperfine splitting of the proton of the C--H group and showed that this splitting is proportional to the spin density at the p.-orbit of the cLtrbon atDm in the C--H Proup. In the first approximation the co6fficient of proportionality Q., between the hyperfine splitting and the spin density ie const-stat for all arom~~c 68329 Diste,Ai-.ition of Spin Density in the Chromiun Dibenzene Gation SOV/51-8-1-36/40 radicals and Ion-radicals. If it is assumed that the coefficient CA is the same in metal-aromatic-compounds, then the observed proton hyperfine splitting (3.6 Os) shows that the spin density in the pt-orbit of a single carbon atom Is 0.16. Since all protons are equivalent, the spin 4onsity at all the carbon atoms is the same. It follows that theli'4n density in theT; system of both benzene rings is equal to 1.92. In order to reduce the total spin density of the whole molecule of the chromi%im dibenzene cation to unity we have to assume that the spin density at the atomic orbits of chromium is 0.92 and its sign is opposite to the sign of the density at the benzene rings. The requirement of normalization of the spin density to unity follows from the fact that the chromium dib-snzeae cation has only one unpaired el ectron (Ref 5). The authors show that other evidence (Refs 12, 13) also supports the suggested spin density. Acknowledgments are made to Yu.A. Sorokin and G.A.

The molar ratios of anhydride to glycol were7 of 1:1 to 1:2.5 and the reaction duration was 2-6 hr. The properties of the reaction products as coatings were compared to those based on phthalic anhydride. The rates of the polycondensation reaction and the energies of activation are graphed and tabulated.! It was found that this polycondensation is a two-stage reaction. The first of these stages is fast, almost independent of temperature, and leads to the formation of the acidic esters. The second stage, h 'ighly temperature dependent, was found to be a sec- ond order reaction.

The kinetics of thermal degradation were studied in the 200-4001C range by followi ng the pressure drop in the,system and by IR spectros- copy. Oxidative degradation was studied in the 180-:2400C range and at an initial oxy- gen pressure of 200-500 mm lig. The low values of the activation energy of thermal degradation in all polyesters indicate that the process proceeds via a complex mecha- nism. The involvement of the free radical:type inte:rmediates in the thermal degredatic is suggested. The IR spectra indicate that thermal degradation in polyesters involves the cleavage of the C-0 bonds of the eater groups.

TITLE: Investigation of the Dibenzene-chrome Derivatives by the Method of Paramagnetic Electron Resonance PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheakaya, 1959, Vol 23, Nr 10, pp 1263 - 1264 (USSR) ABSTROT: In earlier papers (Refs 1-3) it has already been, shown that in highly diluted dibenzene chrome solutions the interao'6ion be- tween the unpaired electron and the protons of the benzene rings,. which are in dixe_,3t connection with the metal (chrome-) atom, manifest themselves by a distinct hyperfine structure of the spectrum of paramagnetic electron resonance. It has already been shown that the introduction of a substituent into the benzene ring influences neither the g-factor of the compound nor the amount of the hyperfine splitting (3-~�O-5 Gs). It was further found that the dissolving temperature, the nature of the solvent or that of the substituent introduced into the benzene ring influen-ries the width of the hyperfine structure component. Further investigations concerned the spin density Card 1/3 distribu',_J:o-i of the unpaired electron in the molecule, the Investigation of the Dibenzene-chrome DerivatJves by SOV/413,;L-3-10-35/39 the Method of Paramagnetic Electron Resonance hyperfine splitting, as well as the width of the hyperfine structure component. In 'his :connection, several details, which were obtained from referenoes 1-8 are briefly discussed. Further investigations concerning hyperfine splitting were carried out with the cation of dibenzene chrome with cyclo- hexyl substituents in both rings. It was found that at low temperatures of the solution of this compound an additional triplet splitting (1+0.5 Ga) of each hyperfine structure com- ponent occurs. It is caused by the interaction of the unpaired electron with two protons of a cyclohexyl substituent. An in- vestigation of the influence exerted by various factors on the width of the hyperfine structure component gave the fol- lowing result: A considerable dilution of the solution with a reduction of temperature loads to a monotonic improvement of the spectral resolving powAr,, i.e. the width of the hyperfine structure component decreaaea. In some solvents (e.g. alcohols) an anomalous temperature dependence of the spectral resolving power is found; this might be explained by a complex formation between the dibenzene chrome aations and the molecules of the Card 2/3 Investigation of the Dibenzene-chrome Derivativ-es by SOV/48~-23-10-35/39 the Method of Paramagnetic Electron Resonance solvent.

The studies were J made with conoenArated solutions (more than 0.02 mol/1) (solvents - ethanol, pyridine, acetone) by means of a spectro- meter with a high-frequency modulation of the magnetic field (Ref 5)- It was observed that at the gradual lowering of temperature the -width of the superfine structural component (A H) of (I~ and (IS) is constantly reduced, and,reaches a minimum at -50, -80 C- When the temperature is lowered beyond that, the width increases again. In all solutions of (1) and * Card 1/2 (11) investigated, two additional lines were observedn They SOV/76-3;-9-37/35 On the Temperature Dependence of the Width of the Component of Superf'-ne Structure in Electron Paramagnetic Resonance Spectra came about by a superfine fission at the Cr53 isotope. It is stated that there exists an anisotropy of the g-factor a.-id a superfine siructure in the chromium--aromatio compoun, Besides the temperature reduction, there are two more re _;one for the extension of the com;onent of superfine structure: One is due to the formation of stable complexes or solvate shells, and the other one is in no connection with the exchange interaction. In order to solve thin problem it will be neces.- sary to carry out studies with diluted solutions in which the latter effect is negligible. It is ascertained -that a temperature reduction may cause a better dissolution of the superfine structure than a dilutiong and if this comes about it can be observed with less sensitive instruments.

In the substances described here. which give an a. P. r. signal, this signal is the smaller, the smaller the number of Jerrocene links is. This signal vanishes in 2). Polymers with a low molecular weight give no e. p. r. signal 'in the solution (bonzene), but in solid state. This is explained'by the fact that the intramolecular interactions cause In solid state a conjugation of the adjacent polymer molecules. This causes for its part an 9. p. r. signal.* All polymers Oard Vfk5- 23654 5/020/61/137/006/013/020 Synthesis and some B103/B217 giving this signal show a single symmetrical line of the e. p. r, of the Lcrenz type.

This line becomes broader on reducing the measuring temperature. Its width is changed moat considerably in low-molecular iialymers. The authors believe the nature of the measured signals to be unclarified, they cannot maintain that the number 11 of the unpaired electrons per I member, deter- mined by a comparison with the standard, corresponds to their actual number.

Vol 8, Nr 1, pp 137-140 (USSR) ABSTRACT; Chromium dibenzene, is a representative of a new type of compounds known as sandwich type compounds. In these compounds the metal atom is not bound to a single carbon atom but to the wholan system of an aromatic hydreearbon (Refs 1, 2). The present paper deals with distribution of the spin density in- the chromium dibenzene cation. The spin density was found from the hyperfine structure (h.f.s.) from electron paramagnetic resonance (&.p.r.-) spectra of strongly diluted solutions of the chromium dibenzene cation and solutions of chromium dibenzene cations with loopropyl and cyclohoxyl substituanto in both benzene rings. Fig 1 shows the e.p.r. spectrum of the chromium dibenzene, cation obtained in an acetone solution at -700C. From the ratio of the h.f.s. intensities and the constancy of the hyperfine splitting (3.6 � 0.5 0e) it follows that the unpaired electron interactswith protons of both benzene rings; all twelve protons in these rinGs act 'in the same way. Voyevodskiy, Molin and Chibrikin (Ref 7) found that Card 1/3 in#-.roduction of a hydrocarbon substituent did not alter the tuagnitUde 68329 SOVI51-8-1-36140 Distribution of Spin Density In the Chromium Dibenrene Cation C,-Nrd 2/3 of the hyperfine splitting &nd that the niuiber of the h.f.s. components represented the number of the remaining protons in both benzene rings. A more detailed Investigation carried out by the present authors showed that in the spectrun of the chromium dicumene cation (Fig 2, at -900G) each component of the ring proton h.f.s is split, into a triplet with a separation close to 1.0 Oe. This additional triplet splitting is due to splitting on both ot-protons of the isopropyl substituants. Similar effects were observed in the case of the chromium dibenzene cation with a cyclohexyl oubstituent in both benzene rings. Bubnov and Chibrikin (Ref 8) reported additional hyperfine splitting in the spactrum of the chromium dibensens cation in solution, which vas ascribed to intoraction of the unpaired electron with a magnetic moment of the Cr53 isotope which is present In the natural chromium. This -was also found by the present authors and is shown in Fig 3; the hyperfina splitting between the h.f.s. components of chromium amounted to 19.0 Oe. All the a.p.r. spectra reported by the authors were recorded with a spectrometer described earlier (Rof 9). McConnell and Chestnut (Ref 11) suggested an indirect interactlon to explain hyperfine splitting of the proton of the C--H group and showed that this splitting is proportional to the spin density at the p.-orbit of the cLtrbon atDm in the C--H Proup. In the first approximation the co6fficient of proportionality Q., between the hyperfine splitting and the spin density ie const-stat for all arom~~c 68329 Diste,Ai-.ition of Spin Density in the Chromiun Dibenzene Gation SOV/51-8-1-36/40 radicals and Ion-radicals. If it is assumed that the coefficient CA is the same in metal-aromatic-compounds, then the observed proton hyperfine splitting (3.6 Os) shows that the spin density in the pt-orbit of a single carbon atom Is 0.16. Since all protons are equivalent, the spin 4onsity at all the carbon atoms is the same. It follows that theli'4n density in theT; system of both benzene rings is equal to 1.92. In order to reduce the total spin density of the whole molecule of the chromi%im dibenzene cation to unity we have to assume that the spin density at the atomic orbits of chromium is 0.92 and its sign is opposite to the sign of the density at the benzene rings. The requirement of normalization of the spin density to unity follows from the fact that the chromium dib-snzeae cation has only one unpaired el ectron (Ref 5). The authors show that other evidence (Refs 12, 13) also supports the suggested spin density. Acknowledgments are made to Yu.A. Sorokin and G.A.
