Ultrafast Chemical Dynamics of Reactions in Beams

Abstract

The purpose of this research was to initiate the field of femtochemistry by interfacing state-of-the-art femtosecond laser systems to a beam system. This plan allowed us to study, for the first time, the ultrafast dynamics of chemical bond breakage in reactions under collisionless conditions (beams). The success of these experiments, which view the process directly in real-time, created a wealth of information on the nature of the transition state and the resultant internal states distribution. A summary of the achievements together with the list publications is presented in this paper. Keywords: Photochemical reactions; Real time; Transition state high resolution; Unimolecular reactions; Reaction kinetics.
