Time resolved electron spin resonance of spin correlated micelle confined radical pairs - Shape of the anti-phase structure

A new approach to the theory of the EPR of spin correlated radical pairs (S CRP) is formulated. It is based on spectral exchange methods as applied to the two-site model and takes into account explicitly both the motion of one quantum (transverse magnetization) and two quantum coherences (polarizatio ns) of SCRPs. This innovation allows for the interpretation of anti phase s tructure (APS) spectral shape asymmetry and for the transformation of the i nitially created ST0RPM polarization into the APS spectral pattern. The res ults of this method as applied to micellized spin correlated radical pairs have been compared with the exact numerical solution of the corresponding s tochastic Liouville equation and is commented on.
