Long Range Nonadiabatic Couplings and the Cluster-Size Dependence of the Lifetime of Excited Hydrated Electrons

Abstract

The recently observed linear dependence of the lifetime of excited hydrated electrons upon the inverse of the cluster size is explained in terms of a nonadiabatic long range coupling mechanism. It is due to dipolar interactions between the p→s transition and the excitation of the infrared active modes of the solvent water molecules.
