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 of wavenumber, providing a fingerprint-like pattern that can be compared to reference spectra to determine the identity and concentration of the sample.
Applications of IR spectroscopy are widespread, ranging from identifying unknown compounds to monitoring chemical reactions and characterizing the structure regarding polymers, pharmaceuticals, and other materials. The technique is highly versatile with it can be applied to a wide range different kinds of samples, including solids, liquids, and gases.
