UV Absorption

UV absorption refers to the process where molecules absorb ultraviolet (UV) light, causing electrons within the molecules to jump to higher energy levels. Many organic compounds, like those with double bonds or aromatic rings, have specific structures that readily absorb UV light. This property is useful in analytical techniques such as UV-Vis spectroscopy, which helps identify and quantify substances by measuring how much UV light they absorb at different wavelengths. Essentially, UV absorption reveals details about a molecule’s structure based on its interaction with UV light.
