Abstract
Picosecond time-resolved fluorescence depolarization was measured at high p ressures for p-terphenyl (PTP) in n-octane and 1-butanol. The rotational re orientation time (tau(R)) was deduced from these measurements and studied a s a function of solvent viscosity. The viscosity dependence of tau(R) was c ompared with the results predicted by hydrodynamic models. A faster deviati on than predicted from the modified SED slip hydrodynamic model was observe d, (C) 2000 Elsevier Science B.V. All rights reserved.
