 Ultraviolet
Visible Absorption Spectrophotometer |
| Most compounds absorb ultraviolet (UV) and visible (Vis) light. If a compound has color, then it usually means that visible light is being absorbed. Although we can't get much structural information this way, the amount of light absorbed at a given wavelength is related to how much of the compound is there. UV-Vis spectrophotometers are often used to tell us how much is present if we know compound's identity. |
