| Research Abstract |
Time-resolved X-ray absorption fine structure (XAFS) was conducted to investigate transient structure change in the triplet metal-to-ligand charge transfer (3MLCT) state of [RuII(bpy)3]2+. Previous studies of the 3MLCT state have mainly been performed using optical spectroscopic methods, from which it is difficult to estimate the molecular structure with atomic resolution. XAFS reveals the atomic distance between the absorbing atom and coordinated atoms via extended X-ray absorption fine structure (EXAFS). XAFS gives also the valence of absorbing atom by X-ray near edge structure (XANES). The results show the detailed information about the transient electronic state and local structure that is difficult to track by conventional spectroscopy.
