IR Spectroscopy (Chapter 5)

Infrared (IR) spectroscopy is an analytical technique used to identify and study chemical substances based on the absorption of infrared light. In IR spectroscopy, a sample is exposed to infrared radiation, which causes molecular vibrations, such as stretching and bending of chemical bonds. Different functional groups within a molecule absorb specific wavelengths of infrared light, resulting in a unique spectrum that acts as a "fingerprint" for the compound. This technique is commonly used for identifying functional groups, analyzing molecular structures, and determining sample purity.
