[Influence of Viscosity upon the Anisotropic Fluorescence and Lifetime of trans-StUben]

The fluorescence anisotropy r and lifetime Tp of transstilbene in different solvents has been measured and the dielectric relaxation time from Perrin and Debye equations has been determined. The fluorescence lifetime in the viscosity region from 0.321 to 61.92 Nm _2 s, varies between 30 and 152 ps.
