 Ultraviolet–visible spectroscopy of stereoisomers

Ultraviolet-visible (UV-Vis) spectroscopy is a powerful analytical technique used to measure the absorbance of ultraviolet and visible light by a substance. When applied to stereoisomers, it can help distinguish between different conformations and configurations of molecules that have the same molecular formula but differ in the spatial arrangement of their atoms. ### Key Concepts: 1. **Stereoisomers**: These are compounds that have the same molecular formula and connectivity of atoms but different spatial arrangements.
