Effect of unsymmetrical substitution on the nuclear quadrupole resonance spectra of trivalent antimony

Abstract

Very strong asymmetrization of the electron distribution on the central atom occurs for the unsymmetrically substituted compounds of trivalent antimony, which is expressed in a noticeable increase of the asymmetry parameter and the constants of the quadrupole bond for121Sb and123Sb when compared with compounds of the SbX3 type.
