Paper Abstract

Photon stimulated desorption of NO molecules at modified Pt(111) surfaces are investigated by reflection-absorption infrared spectroscopy (RAIRS) and resonance-enhanced multiphoton ionization (REMPI). The initial adsorption state of NO is probed by RAIRS and the final-state distribution is measured by REMPI. Coadsorption with N, O, and Ge atoms on Pt(111) appreciably influences the initial adsorption state of NO and the final-state distribution of photodesorbed NO. The rotational temperatures are substantially lowered by coadsorption with O and N atoms. Effects of initial geometric and electronic states on the desorption dynamics are discussed.
