Time-Resolved Probes of Adsorbate-Substrate Energy Transfer

Abstract

Recent advances in time-resolved measurement techniques have provided new molecular level insights into energy transfer processes. Through pump-probe measurements of excited state recovery, direct measurements of lifetimes and energy transfer pathways have been achieved. In vapor, liquid, and condensed phase studies, these techniques have provided the capability of following the evolution of molecular processes. Application of similar techniques to clarify the timescales and pathways for energy transfer processes at surfaces is only now beginning to meet with success.1,2
