| Outline of Final Research Achievements |
We have developed a method to analyze geometries and molecular orientations of photoinduced charge-separated states by detections of the magnetic interactions by using the time-resolved paramagnetic resonance (TREPR) methods. We have employed multi-frequency TREPR spectroscopy to characterize the geometries and the electronic coupling of the photoinduced primary charge-separated states generated in the photosynthetic reaction centers and in the photosystem II reaction center of spinach. We have clarified molecular mechanisms of the efficient charge generations and of the preventions of the energy-wasting charge-recombinations.
