摘要：

The dynamics following two-photon excitation of an aqueous halide ion are studied via quantum simulation. Two channels for photodetachment are observed: a direct detachment via a very early time non-adiabatic transition and a delayed adiabatic detachment from the lowest-lying charge-transfer-to-solvent state. Fast, non-diffusive, geminate recombination of electron-halogen contact pairs arising in the latter case dominates the kinetics of deactivation of excited state ions. Calculated transient emission spectra show a distinct signature for the adiabatic detachment.
