UV Spectroscopy- Principle, Instrumentation, Applications Spectroscopy is the measurement and interpretation of electromagnetic radiation absorbed or emitted when the molecules or atoms or ions of a sample moves from one energy state to another energy state. Broad classifications ii. What is the wavelength range for UV spectrum of light? This absorption spectroscopy uses electromagnetic radiations between 190 nm to 800 nm and is divided into the ultraviolet (UV, 190-400 nm) and visible (VIS, 400-800 nm) regions. Spectroscopy is based on the interaction between light and matter.
