Abstract
Desorption of NO molecules chemisorbed on a Pt(001) surface at 80 K induced by ultraviolet laser is investigated by the resonance-enhanced multiphoton-ionization technique. The desorption yield of neutral NO versus pump-laser fluence indicates a single-photon process. The translational, rotational, and vibrational temperatures are approximately 650, 300, and 1200 K, respectively. These values do not significantly differ at λ=193, 248, and 352 nm, suggesting that the initial step of photodesorption is a substrate-valence-electron excitation.Keywords
