โœฆ Synopsis

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 dephasing rate is considerably faster for this system than the energy relaxation rate. These conclusions are compared with the results of a recent experiment.

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 t

Infrared double resonance and saturation techniques have both been used to measure the V-T relaxation of the 19 mode of CH3F in dilute solution in the cryogenic liquid hosts 02 and Ar. With the former technique, a relaxation time of 375 + 35 ns is found in liquid 02 while in liquid Ar the relaxation
