Infrared spectroscopy

Infrared spectroscopy (IR spectroscopy) is an optical technique that detects molecular bond vibrations and rotations upon absorption of infrared light. Because different chemical functional groups absorb IR light at different frequencies, IR spectroscopy can be used for chemical structure analysis, chemical fingerprinting and chemical imaging.
