Abstract
FUV spectroscopy in the 145-200 nm region has recently been a matter of intense interest because many kinds of materials in the condensed phase. Rapid progress of the studies has been introduced by the development of attenuated total reflection spectroscopy in the FUV region (ATR-FUV), which has enabled us to measure the spectra in the complete FUV region for liquid and solid samples without facing problems such as peak saturation. Moreover, significant progresses of quantum chemical calculations for electronic excitation states of molecules improve our interpretations of the FUV spectra. We will present an investigation about the FUV spectroscopy for aqueous solutions of highly concentrated alkali-metal salts, named hydrate-melt which can be used as high-performance electrolytes.
