ATR-Far-ultraviolet Spectroscopy-Towards New σ Chemistry
ATR-FUV spectroscopy for condensed states allows one to explore various researches in physical chemistry, analytical chemistry, nanoscience and technology, materials science, and organic chemistry. In my talk I put particular emphasis on following three major topics: (1) Studies of electronic transitions and structure of a variety of molecules, which one cannot investigate by ordinary UV spectroscopy. The combined use of ATR-FUV spectroscopy and quantum chemical calculations allows to investigate various electronic transitions including σ, n–Rydberg transitions. ATR-FUV spectroscopy may open a new avenue for σ-chemistry. (2) ATR-FUV spectroscopy enables one to measure the first electronic transition of water at around 160 nm without peak saturation. Using this band, one can study electronic structure of water, aqueous solutions, and adsorbed water. (3) ATR–FUV spectroscopy has its own advantages of ATR method as a surface analysis method. ATR-FUV spectroscopy is a powerful method for exploring a variety of top surface phenomena (～50nm) of adsorbed water, polymers, graphene, organic materials, ionic liquids, and so on. As the recent application of ATR-FUV-UV spectroscopy studies on electronic transitions from σ orbitals in various saturated molecules are introduced first, and then applications of ATR-FUV spectroscopy to studies on water, aqueous solutions, and adsorbed water are discussed. Applications of ATR-FUV spectroscopy to other materials researches such as polymers, ionic liquids, inorganic semiconductors, graphene, and carbon nanocomposite follow.
