Abstract

A model is presented for determining the bond dissociation energy, D0, of a surface-adsorbate complex from collision-induced desorption measurements. D0 is calculated from the minimum collision energy required for desorption by correcting for two energy transfer events using a model based on classical mechanics. The model is tested with measurements made for the CH4/Ni{111} system [Beckerle et al., J. Chem. Phys. 93, 4047 (1990)] and a D0 of 118 meV is found.
