Ultraviolet-visible spectroscopy (UV-Vis)
Ultraviolet-visible (UV-Vis) spectroscopy is an analytical technique used to measure how a substance absorbs light in the ultraviolet and visible regions of the electromagnetic spectrum. When a sample is exposed to light at specific wavelengths, certain molecules absorb energy, causing electronic transitions. By analyzing the absorbed wavelengths and their intensities, scientists can identify and quantify substances, such as chemicals in a solution. UV-Vis spectroscopy is widely used in chemistry, biology, and industry for monitoring reactions, determining concentrations, and studying molecular structures with precision and specificity.
