Vibrational Energy Exchange between Diatomic Molecules and a Surface

Abstract
The problem of the steady‐state vibrational energy distribution of diatomic molecules that temporarily reside on a surface during exposure to a molecular beam is examined according to the rate equations proposed by Klemperer and Herschbach. It is shown that it is possible to obtain explicitly the steady‐state vibrational energy distribution for different vibrational energy distributions in the incident beam and that the vibrational energy accommodation coefficient suitably defined is of a very simple form.
