 Infrared spectroscopy

Infrared spectroscopy (IR spectroscopy) is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. The fundamental principle of IR spectroscopy involves the absorption of infrared light by molecules, causing them to vibrate. Different chemical bonds within a molecule will absorb infrared light at characteristic frequencies, which depend on factors such as the types of atoms involved, the bond lengths, and the molecular structure.
