Probing electronic structures of metal complexes from the ligand side using soft X-ray absorption spectroscopy.

in the solid phase was studied by the XAS measurements with a radiation-induced effect which may cleave the phytol chain. Time-resolved N K-edge XAS measurements at the 100-ps timescale were used to examine the photorelaxation process of iron phenanthroline complexes in aqueous solution. Future directions of studies of various chemical and biological processes that involve metal complexes using N K-edge XAS measurements of ligands are discussed.
