Abstract

Rotational diffusion of fluorene was studied by means of fluorescence anisotropy measurements using a time-correlated single photon counting apparatus. The measured rotational relaxation times in various alcohol solvents were compared with hydrodynamic predictions for prolate spheroidal and asymmetric ellipsoidal shapes in the "stick" and "slip" limits. The rotational dynamics of this molecular system was not predicted by slip or stick hydrodynamics assuming the friction which is proportional to the solvents' viscosities. Some factors that might be responsible for this phenomenon are discussed.
