CLASSICAL AND QUANTUM-MECHANICAL MODELS FOR STARK EXPERIMENTS

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