✦ Synopsis

Rhodamine 6G molecules in methanol. ethanol and \uter xxere excited by 10 ps pulses from a frequency-doubled SdzYAG laser-The fluorescence pol;lrized pamllel and perpendicular to the incidenr hshr v.xs detected with a streak camera. The orientationa relaxation time of rhodamine 6G in rhe e\cired stale has been determined from the time-dependent fluorescence polariz.&ion anisotropy. The rehution rimes agree aith the results of other authors obtained by different methods and confirm the assumption that the orientational rehution in the ground and exited state is similar.
