Abstract: Imidazo (4,5-f] qu-inoline was selected as a model compound becuase
it contains two -potentially active centers,-~dth.respect to the nucleophilic
reagents such as phenyllithium, sodamide, namely positions 2 slid 7- It was
there reagents
established that the quinoline nucleus is rwre reactive torwards
-than.the imidazole nucleus. An assumption'Vas stated th~tt the course of nucleo-
philic attacks is principally determined by ithe. relative,basicity of the aza
group. . Ible nuclear).hilic attack occurs at the carbon atom adjacent to the more
basic nitrogen atom. This assumption was supp'orted,by mQIecul6r orbital calcu-
lations and pKa, values. The positive charge orx~ the ener6y of anionic localiza-
J - tion'-on C - and C7- atoms in a neutral molecule appear.to be oLl no,conseqlence

Chichibabin Reaction"
Rigat KhWya Geterotsiklicheskikh Soyedineniy, No 9, 1972, pp 1252-1263
Abstract o Some I- Ct (or T )-pyxidiyl. and I- C~ (or ~/)-pyridylethyl-
benzWdazoles were synthedized and their reactivity to methyl iodide and
sodanide was studied. The results are discussed fron the point of view
of basicity, the magnitude of the dipolamonents, the tiutual effect of
heterorings and the distviblation of electron dens.iiy in then, calculated
or estimated from the relative position of the chemical shif ts in the para-
magnetic resonance s etra. The benzimidazole system enters into the Chichi-
pe
babin, reaction appreciably more- easily than the pyridi;ie system. On the
basis of the paramagnetic resonance spectral. data, for IAses and cations of
pyridine and benzimidazole it is proposed that this phenomenon arises from
the high degree of polarizability of the, G-ft' bond, of I the benzimidazole by
comparison with the Oull bond of.thepyridine ontheir coordination with

Abstract: The paper discusses the actionlof a microwave electric field on
the crystal lattice of a semiconductor material. Conditions are discussed
under which the applied field.transfers,energy to the electron ga~; without
disturbing the crystal lattice. The
requirements are reduced to three: a
strong applied field, a long mean free path, and elastic scattering. This
situation is satisfied with modern semiconductor sinjzle~crystals in which
the electrona can be heated to 2000*C with the applicatton of a field of a
few kv/cm, while the crystal 1attice rciriains 4tt rom. teriTerature, and i-f

the semiconductor is ccoled to liquid nitrogen temperatures, the electron gas
is heated to 5000*C by the same Ifteld. The production of high field inten-
sity domains (Gunn effect) is explained, as well as the~generation of high
thermoelectroy-otive forces by an effect analogous to thoi therzacouple ef-

"Galvanomagnetic Recombination Effect in an Inhomogeneous Magnetic Field"
Vilnius, Litovshiy rizicheskiy Sbornik, No 3, 1973, pp,:393-399
Abstract: An intrinsic semiconductor in a.homogeneous magnetic fteld changes
its resistance as a consequence of the redistribution of the cur;:ent carriers
along the cross section of a sample having different surface recombination
rates on opposite sides, one.of them being low. Carrier redistribution takes
place at a distance ~o of the diffusion length.
In an inhomogeneous magnetic field a change in resistaixe takes place when
the surface recombination rates on both bides are high-
In this paver the authors solve the problem for the case of weak fields and
a linear variation of the magnetic fieldc. It is shown that the change in
concentration in this case occurs not only at a distance from the sides of
the. sample but also along its entire cross section. The change in resistance
taker, place also when the _,urface recombination rates (~n both sides are W-gh,

Abstract: The galvanomagnetic recombination effect in defined as
the phenomenon occurring in'semimiduc-I'l-ors with both signs of cur-
rent carrier when there is a loss of equilibriwn, of current car-
riers in a magnetic field due to the different~velocities of sur-
face recombination in facing boundaries. A table iB Civen for

applied to certain particular cases, without taking the phase
shift into account. The authors also measured~some characterist-
ics of sensors of the Calvanomagnetic recombination effect in a!-
ternating mag-ne tic and electri-c fields at -frequencies less thain
the-critical value; results of.the measurements are given in the
form of curves. One of the functions of this article is -11-1o indi-

PP 45.77460 (from -Uh-Fizika, No. 1-1, 1971, Abstrict No. 11EI 109)
Iranslation: With angular incidence of an electromagnetic wave on
&magnetized solid plasma of laminar n-InSb, two-reflected waves
are,obtained, one of which is Dropagated perpendicular to the
surface of the specimen and is caused by the reflection of the
helicon.from the rear wall of the specimen. The.,experiment was
conducted at a frequency of 38.2 Uz~and a temperaturb of 770 K.
