Vibrational Energy Transfer in Gases. Atom—Diatomic Molecule Collisions

Abstract
The interconversion of molecular vibrational energy and translational energy is studied; the equations of motion describing collinear collisions of a Morse diatomic molecule with a Lennard‐Jones 6–12 atom are integrated numerically. The effects of initial relative translational energy and initial vibrational energy are determined, and vibrational relaxation times are calculated by a Monte Carlo method at three different temperatures and with two different translational energy distributions.
