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.

A careful consideration of the kinetics of simple reacting systems near equilibrium shows that the observable relaxation times of the system involve not only transition probabilities (or rate constants) but also the dependence of these quantities on concentrations. By using a new method to describe the kinetics of 2- and 3-state processes (which introduces a time-dependent distribution function for the reaction co-ordinates) it is shown that, under certain conditions, the concentration-dependent terms can be evaluated in terms of the solution properties of the system.
