This article describes the principles and applications of absorption spectroscopy in the ultraviolet (UV), visible (Vis), and near-infrared (NIR) regions of the electromagnetic spectrum. UV/Vis spectroscopy is used for (1) quantitative measurements of material components and precursors and (2) characterization of the optical and electronic properties of a material. Most measurements can be made with commercially available spectrophotometers and sampling accessories.
