Glossary Infrared Spectroscopy

technique analyzing chemical bonds via infrared light absorption

Infrared Spectroscopy (IR Spectroscopy) is a technique used to identify and study chemicals by analyzing how they absorb infrared light. When infrared light is passed through a sample, different chemical bonds within the molecules absorb specific wavelengths, creating a unique spectrum that acts like a molecular fingerprint. This method is widely used in chemistry and biology to determine the composition and structure of substances.
