Molecular Collision Cross Section Due to Quadrupole-Induced Dipole and Dipole-Induced Quadrupole Interactions

Abstract

A theory for molecular collision cross section due to quadrupole-induced dipole and dipole-induced quadrupole interactions has been developed following the Anderson—Tsao—Curnutte approach. The OCS–He, OCS–Ar, and HCl–Ar collisions are discussed. For HCl–Ar collisions, μ1q1α2 interactions have been found to be important, whereas in OCS–He and OCS–Ar collisions these are negligibly small.
