Abstract

This paper reviews our understanding on the dynamics of vibrational heating and bond- breaking within a universal electronic mechanism, i.e. the multiple scattering mechanism induced by hot-electrons generated by femtosecond laser pulses. A few theoretical approaches, based on the reduced density matrix and a resonance model of electron-molecule coupling, are briefly sketched and discussed, and qualitative features of vibrational heating and bond- breaking are emphasized. Two illustrative examples of vibrational heating of CO stretch on Cu and O₂ desorption from Pt(111) demonstrate that the dynamics of electronic and vibrational heating can be partly revealed by the yield and final state distribution analysis.
