摘要：

Electron spin polarization of light-induced radical pairs in plant photosystem I is studied by transient EPR following pulsed laser excitation. The time evolution of the transverse magnetization is monitored at various static and microwave magnetic fields. Quantum beat oscillations are observed at early times after light excitation of fully deuterated whole algae Synechococcus lividus. Model calculations for the time profiles, based on the correlated radical pair mechanism, provide information on the spin-spin coupling and lifetime of the secondary radical pair.
