Two pulsed EPR methods for studying spin-correlated radical pairs (SCRPs) transiently generated in photochemical reactions are presented. One is two dimensional (2D) EPR nutation method which uses anomalous flip angle dependence of SCRPs for microwave (MW) pulses and the other is application of the so called 2D J spectroscopy in NMR to studies of paramagnetic SCRPs. The methods were applied to observation of the SCRP generated in the photoinduced electron transfer reaction between zinctetraphenylporphyrinsulphonate (ZnTPPS) and duroquinone (DQ) in cetyltrimethylammonium chloride (CTAC) micellar solution in which SCRP alives for a relatively long period at the early stage of the reaction processes.
