Molecular constants of Group V hydrides by Green's function analysis

Abstract

The evaluation of potential energy constants, mean amplitudes of vibration, rotational distortion constants, and Coriolis coupling constants for Group V hydrides was attempted by the method of Green's function analysis. It is shown that these molecular constants can be calculated without recourse to any specific force field. The values of these molecular constants obtained by this method are, in general, in very good agreement with those obtained by the usual normal coordinate analysis.
