Photodissociation experiments have become one of the most valuable tools in chemical physics for the purpose of understanding how excited electronic states couple to the dissociation continuum. These experiments, and the the ory developed to explain them, have yielded considerable insight into the variety of dynamical processes that occur subsequent to electronic excita-tion [1]. From these studies, one hopes to obtain bond dissociation ener-gies, characterize the symmetry of the excited state, measure the product branching ratios, and determine if the excited state undergoes direct disso-ciation on an excited-state surface, predissociation via another excited state, or internal conversion to the ground state followed by "statistical" decay to products.
