In studying the radiationless energy transfer between unlike molecules (heterotransfer) in fluid and rigid solutions the fluctuations of the concentration of the acceptor molecules, as well as the dependence of the probability of resonance excitation energy transfer on the mutual orientation of the transition moments of the interacting donor and acceptor molecules have been taken into account. With these and the assumptions of the shell model of a luminescent centre (A. Kawski and J. Kaminski, Z. Naturforsch. 29 a, 452 [1974]) one obtains the Förster expression for the quantum yield of the donor fluorescence quenched by foreign absorbing substances

Abstract A formula for the donor photoluminescence decay time in its dependence on the concentrations of donor D and acceptor A has been derived from equations for the non-radiative excitation energy transfer between randomly distributed donor and acceptor molecules within a nonactive medium. In the limit [D]/[A] → 0 the formula becomes identical with that of Galanin [7], while in the absence of concentration quenching the fluorescence decay time does not depend on the concentrations.
