Collision dynamics for an asymmetric top rotor and a linear rotor: Coupled channel formalism and application to H₂O-H₂

Abstract

The close coupling formalism and the approximate coupled states formalism for collisions of an asymmetric top rigid rotor and a linear rigid rotor are reviewed. Calculations for excitation of H2O by H2 using a recent accurate, ab initio potential energy surface are presented. © 1995 American Institute of Physics.
