The photoexcited process for NO chemisorbed on Pt surfaces is presented. Desorption and dissociation induced by nanosecond-pulsed visible and ultraviolet laser irradiation have been investigated using angle-resolved photoelectron spectroscopy, reflection-absorption infrared spectroscopy and a resonance-enhanced multiphoton ionization technique. It is found that the photoexcited process shows high reaction selectivity depending on the surface structure and the adsorption site.
