Study of UV resonance Raman spectroscopy with the aid of the Attenuated total reflectance spectroscopy in the FUV region

UVRR spectra compared with ATR-FUV spectra

Abstract Text: Ultraviolet resonance Raman spectroscopy (UVRR) has so far been used for the structural analysis of proteins. If the excitation light is extended to shorter wavelengths, it can be used to study the structure of sugars and lipids. In the present state, FUV spectroscopy has rarely been studied on water and aqueous solutions. Still, the complementary relationship between FUV spectroscopy and UVRR allows us to effectively promote the investigation of the relationship between electronic state and structure in the liquid state. For example, FUV spectral data is used to determine the excitation wavelength of UVRR. On the other hand, it is expected that the UVRR excitation wavelength dependence will provide helpful information for analysis, such as attribution to the detailed structure of the bands in the FUV spectrum. We have developed the FUV spectra for water and aqueous solutions using the attenuated total reflection technique and interpreted the FUV spectra using quantum chemical calculations.
