Outline of Final Research Achievements

Molecular oxygen is produced from water by a manganese cluster in photosynthesis. This process of the water splitting and oxygen evolution is the most important chemical process in photosynthesis. In this work, a high-frequency ESR spectrometer, which enables us to detect the manganese cluster selectively, was improved. This facilitated the ESR detection of desired electronic states for the manganese cluster.
