Phillips, T.R., S. Maluendes, and, 1995: Collision dynamics for an asymmetric top rotor and a linear rotor: Coupled channel formalism and application to H2O-H2. J. Chem. Phys., 102, 6024-6031, doi:10.1063/1.469337.
The close coupling formalism and the approximate coupled states formalism for collisions of an asymmetric top rigid rotor and a linear rigid rotor a re reviewed. Calculations for excitation of H2O by H2 using a recent, accurate, ab initio potential energy surface are presented.
