Ultrafast Laser Spectroscopy of Chemical Reactions


Ultrafast laser spectroscopy has extended reaction-dynamic studies into the picosecond and femtosecond time domain, allowing for experimental observations of transitory fragments that occur during collision or half-collision. This ability to observe molecular reactions allows real-time viewing of energy redistributions, measurements of state-to-state rates, and tests of microscopic statistical theories as prescribed by potential energy surface (PES) considerations. In this article, the focus is on unimolecular reactions. Recent advances in the studies of "oriented" bimolecular reactions and "transition states" of elementary reactions are also briefly considered.

The majority of the work presented in this review on unimolecular reactions has been published in collaboration with Norbert Scherer and Lutfur Khundkar. Without their efforts and dedication to the development of the techniques, this article could not have been written. We wish to thank professors C.B. Moore and R.N. Zare for stimulating discussions and for communicating unpublished work. We also thank M. Dantus for his efforts on Figure 1.
