| Research Abstract |
Local electronic structures of weak molecular interaction systems such as molecular clusters, liquids, and organic molecular solids were investigated by soft X-ray absorption spectroscopy and resonant Auger electron and emission spectroscopy after core excitation processes. The local structures of rare gas clusters and Kr/Xe mixed clusters were revealed by soft X-ray photoelectron spectroscopy. We developed a liquid cell for the soft X-ray absorption spectroscopy in a transmission mode, and revealed hydration structures of alkali metal cations in aqueous salt solutions. We also investigated the site-specific inter- molecular interaction in crystalline phthalocyanine films by X-ray emission spectroscopy.
