Abstract
Time-resolved techniques are applied to issues of vibrational energy transfer at surfaces. Primary attention is given to the relaxation of vibrationally excited diatomic adsorbates on metals. The sensitivity of the vibrational decay rate to the number of metal atoms in the solid is demonstrated. Preliminary results for the transient response of CO on Pt(111) are also reported. This latter measurement demonstrates the recently developed capability of monitoring adsorbate energy transfer processes at well defined surface sites. The observations appear to be consistent with relaxation through the excitation of electron/hole pairs in the substrate.
