Infrared (IR) spectroscopy

Definition

Infrared spectroscopy is a technique used in organic chemistry to determine the molecular structure of compounds by measuring the absorption of infrared light at different wavelengths. It identifies functional groups within molecules based on their vibrational transitions when exposed to IR radiation.
