Abstract The fluorescence anisotropics (FA) r and the lifetimes of p-terphenyl in different solvents have been measured, the effective volumes and the rotational relaxation times being determined. The deviation from the linear dependence of 1/r on 1/η (η-viscosity of the solvent) may explained by the length of the p-terphenyl molecule. The FA measurements were carried out by a method with an Arago compensator, a new method of the automatization of measurements being employed.
