THE USE OF THE CURRENT-DENSITY IN THE ANALYSIS OF MOLECULAR PHOTODISSOCIATION

We have performed time-independent quantum mechanical calculations wit hin the driven equation approach to photofragmentation processes. By e xtending our previous work on the analysis of photofragment flux, we c alculate the quantum mechanical current density and related quantities from the time-independent wave function. We apply the method to two m odel problems: CH3I, where the dissociation dynamics are dominated by a crossing of two excited state potentials, and CH3ONO, where a local minimum in the excited state potential, which is located near the Fran ck-Condon region, gives rise to a series of strong vibrational resonan ces in the absorption spectrum.
