摘要：

A mechanism describing photo-induced desorption triggered by substrate excitation is presented. Ln this mechanism adsorbate motion is described quantum mechanically and desorption is considered to occur due to energy transfer from the electronic to the nuclear degrees of freedom via non-adiabatic couplings. Considerable insight is gained into experiments on photo-induced desorption of NO and CO from transition metal surfaces.
