UV/VIS Spectroscopy - an overview | ScienceDirect Topics
Ultraviolet–visible (UV–vis) spectroscopy encompasses absorption spectroscopy and reflectance spectroscopy in the UV–vis spectral region. Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb ultraviolet or visible light energy and be excited to higher anti-bonding molecular orbitals.
Ultraviolet–visible spectroscopy - Wikipedia
A UV-vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in …

UV-Visible / UV-Vis Spectroscopy Basics & FAQs - Agilent
Ultraviolet-visible (UV-Vis) spectrophotometers use a light source to illuminate a sample with light across the UV to the visible wavelength range of the electromagnetic spectrum (typically 190 to 900 nm). The UV range normally extends from 100 to 400 nm, with the visible range from approximately 400 to 800 nm.
