Infrared spectroscopy (IR) is based on the interaction of the vibrational frequencies of individual (and groups of) bonds within a molecule with the infrared portion of the electromagnetic spectrum.

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
