Local Electronic Structures in Molecular Interaction Systems Studied by Soft X-Ray Core Excited Spectroscopies

利用软X射线吸收谱和俄歇电子发射谱研究了弱分子相互作用体系（如分子团簇、液体和有机分子固体）在核激发过程后的局域电子结构.用软X射线光电子能谱研究了稀有气体团簇和Kr/H2O混合团簇的局域结构。我们研制了一种用于软X射线透射吸收光谱的液体池，并揭示了碱金属阳离子在盐水溶液中的水合结构。我们还通过X射线发射光谱研究了酞菁晶体薄膜中的分子间相互作用。

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.
