| Outline of Final Research Achievements |
A new electronic structure theory has been developed and applied for core-ionized and core-excitation spectra, which is useful to computationally investigate the X-ray photo-electron and/or the X-ray absorption spectra of transition metal complexes. Based on the density matrix renormalization group algorithm, strong electron correlation originating from the d-electrons has been incorporated to the theory, very accurately. As a result, the theory enabled to computationally analyze the XANES spectra of paramagnetic transition metal complexes, which are often very complicated spectra. The theory has been utilized to practical analyses for structures and electronic states of transition metal complexes in collaboration with experimentalists. This will provide a useful tool to design new catalysts and/or materials from the viewpoint of structural analysis.
