✦ Synopsis

Vibrational deactivation of 0; (v= 1) in lowenergy collisions with Kr is studied within the framework of planar classical mechanics. An approximation in which the relative orientation of the diatom is fixed fails to describe the extent of vibrational deactivation found in exact planar dynamics. We also consider planar Li+/N2 (u= 1) collisions. For this system, in contrast to Kr/O: , the vibrational energy transfer is described quite accurately in the fixed-angle approximation.
