Аннотация:A new method for the fluorescence kinetics analysis is presented in this work. It permits one to obtain new information, both quantitative and qualitative, about the processes in any condensed molecular system. As an example, this method was applied to the light-harvesting antenna of photosynthesizing organisms. The time dependenc of the bimolecular quenching rate of excitons, g, was found. The experimental value of g is obtained without any preliminary theoretical considerations. The character of g time dependence permits one to find the values of the coefficient of the diffusion D = 4 x 10^-3 cm^2 s^-1 and Forster annihilation radius R0 = 100A, within the limits of the diffusive model.
