Vacuum-polarization in μ-mesic molecules of hydrogen isotopes

The electron-positron vacuum polarization corrections to the energy levels of μ-mesic molecules are found. The calculated level shifts ΔE<0.5 eV are an order less than an analogous shift in μ-mesic atoms.     

Amino esters of heterocyclic dicarboxylic acids

The corresponding amino esters and their hydrochlorides and quaternary salts were obtained by the condensation of 2,5-furan- and 2,5-tetrahydrothiophenedicarboxylic acid chlorides with 1-methyl-, 1-ethyl-, or 1-butyl-3-hydroxypiperidines.deceased.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 515–518, April, 1971.     

Mechanisms of the arylation of hydrochlorosilanes under pressure

Conclusions Mechanisms of the silylation of aromatic hydrocarbons by hydrochlorosilanes under pressure have been proposed and substantiated on the basis of the experimental material. In the absence of catalysts, the process occurs according to the mechanism of a reaction of thermal condensation; in the presence of catalysts it proceeds by electrophilic substitution of hydrogen in the aromatic ring, beginning with the dissociation of chlorosilane at theSi-Cl bond. The Si-H bonds serve as an acceptor of hydrogen chloride.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 508–512, March, 1971.     

Classical and quantum gravitational collapse I. General-relativistic dynamics of an ideal liquid

This article is the first of a series of studies devoted to several problems of quantum and classical cosmology as well as to the gravitational collapse of inhomogeneous configurations. In this article we consider the structure of the theory of gravitational collapse and we construct the Hamiltonian of an ideal liquid with an arbitrary equation of state.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 126–130, March, 1977.The authors wish to express their deep gratitude to the participants in the theoretical seminar of Moscow State University (under the direction of Professor D. D. Ivanenko) for a discussion of these results.     

To the quantum theory of chemical activity of the surface of transition metals

The dissociation of a gas molecule and the formation of a new chemical bond upon adsorption of this molecule on the surface of a transition metal are studied using the method of equations of motion. It is shown that both processes involve the formation of a mixed intermediate state during the adsorbate-substrate interaction. The dissociation is caused by a resonance growth of the vibrational mode, whereby the dissociation barrier is determined by the hybridization energy and by the frequency of electron transitions between molecular levels and the d electron energy levels of the metal in the mixed intermediate state. The resonance conditions for the formation of new surface structures are established.
