Abstract

Photofragmentation by intense short-wavelength radiation provides a unique opportunity to study novel decomposition processes in small molecules. In particular, the large photon fluence and short-wavelength force weak single-photon decay channels to be revealed and new decomposition channels via multiphoton excitation to be opened; these channels can involve both ionic and neutral fragments. A complete understanding of the unimolecular dynamics responsible for fragmentation via specific decay channels requires knowledge of (1) the energy state of the parent molecule prior to excitation, (2) the fragment species following decomposition. and (3) the nascent energy states of the fragments.
