| Outline of Final Research Achievements |
Advanced magnetic resonance measurements were carried out for charge distribution and spin dynamics study of electron pairing in the molecular-solids. We clarified possible mechanism of anomalous spin singlet state and competed electronic phases in one-dimensional organic conductor (TMTTF)2X system. We also found that a charge distribution transition for an inorganic system mixed-valence ruthenium complex, in which equivalent electron pairs at room temperature; undergoes inequivalent. We performed high-field ESR measurements for self dope type organic conductors TTFCOO and its derivative, and revealed the origin of radical spin and dimensionality of systems, and itinerant nature of carrier. In addition, we developed spin dynamics investigation in non-equilibrium state, such as light-induced relaxation process study of covalent organic framework (COF).
