Quantum Vibrational Transition Probabilities in Atom–Diatomic Molecule Collisions. V Effects of Mass and Well Depth

Abstract

The method of Cheung and Wilson is used to investigate the dependence of vibrational transition probabilities on atomic masses and on the well parameters of the intermolecular potential. The presence of a well in the intermolecular potential causes quite large changes in the transition probabilities, as do changes in the masses of the colliding particles. Difficulties in using this method on systems having certain unfavorable mass ratios had been noted earlier; a procedure is presented in which these difficulties are overcome.
