Abstract
We present theoretical analyses of two different aspects of the time dependence of the fluorescence Stokes shift in polar liquids. We show that a small deviation from the Debye form for the dielectric relaxation of the solvent can strongly influence the time evolution of the Stokes shift. Using the Davidson-Cole form for dielectric response we find a stretched exponential time dependence as observed in recent experiments. We also show that the shape of the fluorescing molecule can influence the dynamics of solvation.
