Abstract
The influence of a femtosecond laser pulse on an adsorbate molecule-me tal surface system is investigated by considering a time-dependent cou pling between the ground-and excited-state potential energy curves usi ng the time-dependent quantum mechanical wave packet approach. It is s hown that the probability of desorption is strongly dependent on the d uration of the coupling and the image-charge attraction and that it in creases with increase in vibrational excitation of the metal-adsorbate bond.
