Abstract

Time-resolved two-photon photoemission is utilized to study solvation dynamics at two-dimensional interfaces. Collective reorientation of a dipolar adsorbate in the presence of an image potential states electron results in dynamic reduction of the local work function, which is manifest in the observed dynamic changes of the photoelectron kinetic energies.

Abstract

A study shows that time and spectrally resolved ultrafast infrared vibrational pump-probe experiment on the dynamics of hydrogen bond dissociation and reformation in methanol-d clusters dissolved in carbon tetrachloride. It was concluded that hydroxyl stretch excitation lead to hydrogen bond dissociation and has clarified the variety of hydrogen bond breaking and reformation processes and their time scales.
