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

Analyzing Infrared Spectra
Infrared (IR) spectroscopy is a powerful analytical technique used to identify and characterize organic compounds. It relies on the principle that different functional groups within a molecule absorb specific frequencies of infrared radiation, resulting in a unique spectrum. When interpreting an IR spectrum, analysts search for characteristic absorption peaks that correspond to various functional groups, such as alcohols, aldehydes, ketones, and carboxylic acids. These peaks provide valuable information about the structure and composition of the sample.
- As an illustration, a strong absorption peak around 3300 cm-1 indicates the presence of an alcohol group (–OH).
- Moreover, a peak around 1700 cm-1 suggests the presence of a carbonyl group (C=O), which can be found in aldehydes, ketones, or carboxylic acids.
By carefully analyzing the position, intensity, and shape of absorption peaks, scientists can gain insights into the molecular structure and identify unknown compounds.
