Comparison of time-resolved fluorescence Stokes shift measurements to a molecular theory of solvation dynamics

Abstract

The results of time-resolved Stokes shift measurements are compared to a molecular theory of ionic solvation dynamics recently solved by Rips, Klafter, and Jortner [J. Chem. Phys. 88, 3246 (1988)]. Although the theoretical predictions show only semiquantitative agreement with experiment, this molecularly based model provides a satisfying framework for understanding the large departures observed from the behavior predicted by simple continuum treatments of solvation dynamics.
