Using Vibrations to Probe and Control Photoisomerization in Liquids

Abstract

The focus of our AFOSR-funded research during this period of support has been studying the influence of vibrational excitation on electronic-excited-state dynamics in a variety of environments. One of the primary focuses is in liquids, and we have studied excited-state dynamics of vibrationally excited stilbene, of a biomimetic switch, an N-alkylated indanylidene pyrroline Schiff base (NAIP), and of a model compound for excited state isomerization, avobenzone. A unique environment in which we have also explored the effects of surroundings on molecular rearrangements is supercritical carbon dioxide, scCO2. Monitoring the excited-state isomerization of salicylidene aniline has shown the role of viscosity on the course of the dynamics.
