This chapter deals with fundamental aspects of UV-Vis-NIR spectroscopy (in both absorption and emission modes) as well as with representative examples of types of investigations and analyses of electronic spectra for various oxide-based materials of interest in heterogeneous catalysis and photocatalysis. Particular attention has been devoted to highlight the sensitivity of the spectral patterns to the physical-chemical features of the absorbing /emitting centers, that results in a source of rich information on structural and chemical properties of sites responsible for the surface reactivity of the materials.

Abstract
This chapter deals with fundamental aspects of UV-Vis-NIR spectroscopy (in both absorption and emission modes) as well as with representative examples of types of investigations and analyses of electronic spectra for various oxide-based materials of interest in heterogeneous catalysis and photocatalysis. Particular attention has been devoted to highlight the sensitivity of the spectral patterns to the physical-chemical features of the absorbing /emitting centers, that results in a source of rich information on structural and chemical properties of sites responsible for the surface reactivity of the materials.
