Picosecond Laser Chemistry of Materials Adsorbed on Surfaces
Abstract
The research has provided new insights into photophysical and photochemical processes in condensed media, and in the liquid-air interface. Using the new picosecond laser-detection system we monitored the various channels by which photoexcitation energy is used to effect physical as well as chemicals changes in molecular systems. Specifically, we have accomplished the first time resolved studies dealing with photochemical and photophysical processes in the air-liquid interface using surface specific harmonic generation techniques. We also discovered novel relaxation effects on ultrafast photoisomerization reactions due to restricted microenvironments. The results dealing with t-stilbene inclusion complexes with various cyclodextrins provided a model for chemical reactions and molecular motion in restricted environments.
