The O2 adsorbed on Pd(111) is photodesorbed and photodissociated when irradiated with 5.0 eV light. Polar and azimuthal angle-resolved time-of-flight spectra of directly photodesorbed neutral mols. were measured. Both desorption flux and the translational energy depend on the desorption angle. In particular, a marked max. in the translational energy at a polar angle of 60 Deg with C3v symmetry is found for the superoxo species. This behavior apparently is correlated with the binding geometry of the mols. before desorption.
