Femtosecond Dynamics of Chemical Reactions

Abstract

We proposed to use this grant to undertake research in the following three major areas: (a) Dynamics of elementary steps in complex systems. (b) Dynamics of reactions under extreme environment (density, temperature, clustering, etc.). (c) New techniques for direct imaging of structural changes and chemical control of reactions yield and channel. In these studies, the basic approach is based on the development of ultrafast laser (and electron) and molecular beam techniques to examine in real time the nature of the dynamics and structures on the femtosecond time scale. Our goal was to relate these dynamics to features of bonding and mechanisms and to explore the effect of extreme solvation environment on reactivity. Probing and controlling reactions pathways %are key to validating any model of chemical reactivity in complex molecular 5 stems. Theoretical studies in our group and-in collaboration with colleagues elsewhere were an important part of this research activity during the entire period of the grant.
