Abstract
Inhomogeneous broadening of the electronic transitions of dyes in glycerol solutions have been observed by measuring the energy-resolved fluorescence decays as a function of excitation wavelength. The inhomogeneous broadening is shown to arise from a range of solvent-solute orientations, rather than solute conformational distributions. The time-resolved fluorescence data are readily interpreted in terms of a conventional model of inhomogeneous broadening with the inclusion of excited state solvent-solute reorientation. Implications for studies of the dynamic solvation shift are briefly discussed. © 1992.
