โฆ Synopsis
The relaxation of 03(001) by p-and n-Hz was measured over the temperature range 167-424 K. n-Hz quenched ozone more efficiently, with the difference between rate constants increasing with temperature. These observations are explained by a near-resonant V-R process, in agreement with the Sharma-&au theory.

An investigation is made of the vibrational dephasing of a diatomic molecule adsorbed on a surface. Explicit analytic forms for the rate of dephasing by phonons are derived. For comparison, an expression for energy relaxation is given which is appropriate for OH on SiO,. It is found that the dephasi
