Dynamics of electron localization, solvation, and migration in polar molecular clusters.

The time evolution of electron localization, migration, and solvation in ammonia clusters is investigated via computer simulations. The attachment of an electron to a cold molecular cluster in a diffuse weakly bound surface state, the dynamics of solvation, the nonhopping mechanism of migration leading to the formation of an internally solvated state, and the spectral manifestation of these processes are demonstrated.
