Picosecond, time-resolved fluorescence depolarization spectroscopy has been used to measure the rotational reorientation time (tau/sub or/) of electronically excited rhodamine 6G. When the dependence of tau/sub or/ on solvent viscosity for a series of linear alcohols is compared with that for ethanol as a function of pressure over the range from 1 bar to 6 kbar, substantially different rotational reorientation dynamics are found for identical macroscopic viscosities. 31 references, 2 figures, 2 tables.
