Electronic excited-state transport in a system composed of randomly distributed molecules, i.e., rhodamine 6G in glycerol, is experimentally investigated. Time-resolved fluorescence depolarization measurements, which use a fluorescence mixing technique to give subnanosecond time resolution, provide a stringent test for theoretical work on this subject. The results yield an R/sub 0/ value of 50 A for R6G and confirm the results of the recent diagrammatic self-consistent theoretical method. Mean-square displacements and their time derivatives are reported. Energy transport is nondiffusive in the samples studied.
