摘要：

A macroscopic theory for treating the angular disrtibution of desorptive products due to thermal or photo-assisted desorption is reported. The angular distribution has been attributed to either the rotational relaxation of adsorbed molecules or the angular dependence of the rate constant or both. By using the theory of angular momentum, explicit expressions of the desorption yields for the cases of constant temperature or heating with a constant rate were obtained. Based on the theory, some experimental results such as the desorption of CO2 from Pt(III) surface have been explained and the effect of crystal orientation of the substrates was discussed as well.
