Abstract

In the far-ultraviolet region (< 200 nm), many materials have strong absorbance due to electronic excitations and electron transfers intra- and inter-materials. Recently, a new far-ultraviolet spectroscopy based on the attenuated total reflectance method has been developed, and systematic spectral measurements of various liquid and solid samples have been reported. In this tutorial, recent far-ultraviolet studies focusing on functional materials such as titanium dioxide and ionic liquid are summarized. By introducing the original system into the instrument, spectral measurements under light irradiations and electrochemical environments were achieved. The obtained data were related to the material properties such as the photocatalytic activity and molecular behavior near the electrode surface. High applicability and flexibility for various objectives are important advantages of the present spectroscopic technique.
