STRUCTURE OF SPACE CHARGE REGION AT BIPOLAR JUNCTION AND DISSOCIATION OF WATER MOLECULES IN BIPOLAR MEMBRANE MODIFIED BY CHROMIUM(III) COMPOUND

abstract 1041410075 issue 104 pp. 995 – 1014 30.12.2014 ru 976
In the article the mathematical model of the space charge region in the bipolar membrane is considered. The structure of the space charge region under passing of electric current, and without electric current is discussed. The results of experimental studies of water dissociation in the bipolar membrane in the presence of chromium(III) are discussed

ABOUT POLARIZATIONS EFFECTS IN THE RANKS OF ЭХ3 MOLECULES

abstract 0991405018 issue 99 pp. 256 – 265 30.05.2014 ru 1543
Correlations between experimental dipoles moments and values of the difference of first potentials ionization of atoms and molecules (ΔE) for three -coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I ) are described. Exponential functions of dependence μ= f(ΔE) for rows ЭF3 andЭCl3 are received. Within the valence of shell electron pair repulsion theory it is shown, that the molecular dipole moments can be divided to dipol moments of ions of separate atoms, which, naturally changing, are transferred in the ranks of molecules ЭХ3

BOUT REGULARITIES OF CHANGES OF VALENT ANGLES AND POTENTIALS OF IONIZATION IN THE RANKS OF ЭХ3 AND ЭХ2 MOLECULES

abstract 0951401056 issue 95 pp. 980 – 993 30.01.2014 ru 1329
Correlations between values of the differences of first potentials ionization of atoms and molecules (ΔE) and valency angels α for three coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te; X = CH3, SiH3, GeH3) are described in this article. It is shown, that the entered value ΔE can serve as additive measure of change of the valency angle α in the basic and raised stances. We have also established that the functional dependences correlate with changes in the of hybridization of orbitals and the R parameters characterizing the interaction of electronic pairs near the central Э atom
