UV-VIS photometry is used for the quantitative analysis of organic and inorganic compounds and is based on absorption measurements in the UV and visible spectral region of the electromagnetic spectrum according to Lambert-Beer’s Law. Absorption of UV and visible radiation generally results in excitation of bonding electrons. Absorbing species contain structural features (chromofores, functional groups) which are related to transitions (1)∏, σ en n electrons (2) d and f electrons (3) charge transfer electrons.
