Quantum dynamical simulations of nonadiabatic processes: Solvation dynamics of the hydrated electron

Abstract
A new method for simulating nonadiabatic quantum processes is presented. It is suitable for transitions which are not dominated by near crossing of potential surfaces. The method is applied to the calculation of the radiationless transition rate of the hydrated electron from its lowest excited level to the ground state. The results are consistent with recent experimental indications that this process dominates the solvation dynamics of the electron in water.
