Higher Electric Multipole Moments for Some Polyatomic Molecules from Accurate SCF Calculations

Abstract

Higher electric multipole moments for the ground-state electronic configuration of some polyatomic molecules, i.e. CH4, NH3, H2O, were calculated from SCF-HFR wavefunctions using Slater-type orbital basis sets. The calculated results for electric multipole moments of these molecules are in good agreement with the theoretical and experimental ones.
