Fundamentals of Infrared Spectroscopy

Wiki Article

Infrared (IR) spectroscopy is a powerful analytical technique used to identify and quantify chemical compounds based on their characteristic absorption of infrared radiation. When a molecule absorbs IR radiation, its bonds vibrate at specific frequencies. These vibrational frequencies are unique to each type of bond, allowing for the identification of functional groups within a molecule. The resulting spectrum displays absorbance as a function versus wavenumber, providing a fingerprint-like pattern that can be compared with reference spectra to determine the identity and concentration within the sample.

Applications involving IR spectroscopy are widespread, ranging from identifying unknown compounds to monitoring chemical reactions or characterizing the structure of polymers, pharmaceuticals, and other materials. The technique is highly versatile with it can be applied to a wide range variety of samples, including infrared courses solids, liquids, and gases.
