Method of estimating the intense absorption band in the ir spectrum of a molecule type ЭХ3
On the basis of experimental data for the species ЭХ3 compounds (Э=% P, As, Sb; Х =F, Cl, Br, I) it is obtained the quantitative relation between the ionization potentials and dipole moments. Introduced in the asymmetry parameter J, which characterizes the relative size of thedisplacement of the ion...

| Summary: | On the basis of experimental data for the species ЭХ3 compounds (Э=% P, As, Sb; Х =F, Cl, Br, I) it is obtained the quantitative relation between the ionization potentials and dipole moments. Introduced in the asymmetry parameter J, which characterizes the relative size of thedisplacement of the ion Э3- valence shell electrons, allowed to describe the change in value as the dipole moments of the central ions (р^з-) and quadrupole coupling constants e2Qq 3Hlg3compounds. The calculations of the changes of the dipole moments of molecules in excited states and intensities of the absorption bands in the IR-spectra for symmetric vibrations of molecules ЭН1^ were made. |
