摘要：

Based on classical electrodynamic theory, cross sections for surface photochemical processes are derived as a function of the angle of incidence. Using s- and p-polarized light, the expected primary excitation mechanisms, i.e. direct excitation and substrate excitation, can be distinguished. Two examples are shown: for O2 on Pd(111), photo-induced desorption and dissociation at 6.4 eV are unambiguously due to substrate excitation, while for Cl2CO on Pt(111), direct excitation plays an important role in photolysis at 4.4 eV.
