| Outline of Final Research Achievements |
The purpose of this study is to clarify the correlation between the light energy transfer function of the light-harvesting antenna and the protein structure and fluctuation by utilizing our original method. First, the excitation energies of the pigments in the light-harvesting antenna and the excitonic couplings between the pigments were analyzed, and the calculated results were in good agreement with the experimental results. The analysis of the light energy transfer dynamics revealed that the energy transfer is accelerated by the difference in the excitation energy fluctuations of the pigments located in different protein environments. The relaxation process of photosynthetic pigment from highly excited states was also analyzed, and it was found that ligands play an important role.
