Abstract
One of the most attractive systems in molecular dynamics and spectroscopy involves molecules containing two chromophores, in which there are two degenerate diabatic electronic states. Photodissociative systems are especially interesting due to the presence of competition between the fast electronic surface hopping and nuclear dissociative motion. The dissociation serves as a built-in clock for "timing" the rate at which the electronic excitation hops. We represent such a two chromophore system as A1-B-A2 with A1 equivalent to A2. If there is no coupling between A1-B and B-A2 it recovers the simple single chromophore system. When there is coupling between A1-B and B-A2, the two chromophores can "communicate" on an extremely rapid time scale, which complicates the dissociation dynamics. The dynamics of such a system are governed by the rate with which the electronic excitation hops from A1 to A2 or A2 to A1. How fast the electronic hopping happens depends on the coupling strength between the two chromophores. To develop a general technique to probe the dissociation dynamics and the electronic surface hopping is the purpose of the present paper.
