Time-Resolved Photoisomerization Using Femtosecond Stimulated Raman Spectroscopy
Abstract
This grant permitted construction of instrumentation for monitoring excited state photoisomerization using femtosecond stimulated Raman spectroscopy, a particularly informative means of following molecules as they evolve in the excited state. The heart of the instrument is a modern, regeneratively amplified ultrafast Ti:sapphire laser. That laser and associated devices enable experiments using a combination of sophisticated excitation schemes and sophisticated detection methods. These photoisomerization experiments probe the role of excited state vibrations in determining the competition among isomerization pathways and are potentially a means of controlling rearrangements. The experiments provide new insights into fundamental processes, test theoretical descriptions, and uncover the detailed behavior of molecular devices.
