摘要：

We present a model by which the efficiency of T-0-S and T--1-S mixing in a porphyrin-quinone radical pair can be calculated, Rotational diffusion of the quinone relative to the porphyrin, causing a stochastic modulation of the exchange integral J, is included and contributes to the efficiency of triplet-singlet mixing, The model calculations can reproduce the mixing efficiencies extracted from time-resolved X-band EPR measurements.
