Classical and Quantum Mechanical Models for Stark Experiments

Abstract

Abstract The resolution enhancement of photochemical hole burning makes it possible to directly see the effect that an external electric field has on the transition energy resolution of a probe molecule in an organic solid. With an appropriate interpretative model, these experiments can give a detailed picture of intermolecular electrostatic interaction. In this paper classical and quantum mechanical models are reviewed and applied to the same data set. We demonstrate that a relatively simple yet microscopically detailed and easily generalized quantum mechanical model can give an atomic resolution map of electrostatic potential at the chromophore site.
