Abstract
This chapter is concerned with recent advances in far-ultraviolet (FUV) spectroscopy of liquids and solids. In the FUV region not only π-π⁎ and n-σ⁎ but also Rydberg transitions may be observed. Using an attenuated total reflection (ATR)-FUV spectrometer, one can measure FUV spectra of almost all kinds of solid and liquid samples. The most fundamental advantage of FUV spectroscopy is that it contains unique information about the electronic transitions and structure of molecules. In this chapter principle, advantages, and instrument of FUV spectroscopy for studies of condensed matters are described first, and then ATR-FUV studies of electronic structure of organic molecules, polymers, and water are reported. To interpret their spectra quantum chemical calculations were carried out. Finally, FUV spectroscopy of inorganic semiconductor powders is discussed. ATR-FUV spectroscopy has opened a new avenue for σ chemistry.
