摘要：

The dynamics of vibrational heating and desorption induced by multiple inelastic hot electron scatterings is investigated by a microscopic quantum mechanical approach. Numerical simulations are found to be in good agreement with experimental results of O-2 desorbed from Pt(111) by femtosecond laser pulses. The subpicosecond response time of the desorption probability is shown to arise directly from the dynamics of vibrational heating of the molecule-surface bond.
