ultraviolet spectroscopy

Ultraviolet (UV) spectroscopy is a technique used to analyze substances by measuring how they absorb ultraviolet light. When UV light passes through a sample, certain molecules absorb specific wavelengths, causing electrons within those molecules to jump to higher energy levels. By observing which wavelengths are absorbed and how much, scientists can identify and characterize different compounds, especially those with conjugated systems like vitamins, pigments, or proteins. This method is valuable because it provides quick, non-destructive insights into a substance's composition and structure.
