Abstract
A model of photodesorption due to a laser resonantly coupled to an internal vibration mode of the adsorbed molecule is considered. Contrary to works of Gortel, Kreuzer and collaborators1,2 the model accounts for an anharmonicity of the internal vibration, broadening of energy levels of a zero-order Hamiltonian, and partly for multiphonon nature of the resonant heating mechanism. The importance of these features of the model was earlier demonstrated by the author and coworkers for thermal desorption3 and laser-stimulated desorption (LSD) through the excitation of the surface bond.4
