Time-resolved nonlinear spectroscopy and vibrational dynamics at surfaces: the Si-H stretching vibration for H/Si(111)

Abstract

The study of vibrational dynamics of molecules adsorbed on surfaces is newly emerging.1 It follows the earlier development of vibrational dynamics studies in gas and condensed phases. Of interest are the vibrational lifetime, which indicates the inelastic coupling with the substrate, and the dephasing time, which reflects the elastic surface perturbations. In particular, vibrational relaxation might affect the reactivity of adsorbates as well as their diffusion and desorption rates.
