Picosecond Photofragmentation of Tri- and Tetraatomic Molecules: Measurement of State-to-State Reaction Rates

Article abstract of DOI:10.1021/j100268a001

In this Letter, we report our first results on the picosecond measurements of state-to-state rates of reactions, involving three- and four-atom molecules.These photofragment reactions are ICN -> I + CN and NCNO -> NO + CN.In these experiments, we use one picosecond pulse to initiate the photolysis and a second pulse to probe the produced fragments in their internal vibrational/rotational states.Results are presented for molecules in bulbs and beams, and comparisons with unimolecular theories are given.
