Infrared (IR) spectrometry is a powerful analytical technique employed to identify and quantify chemical compounds. It exploits the interaction of infrared radiation with matter, revealing characteristic vibrational modes of molecules. When molecules absorb IR radiation, their bonds vibrate at specific frequencies, generating a unique spectrum. This spectrum acts as a molecular fingerprint, enabling identification and analysis of various substances.

IR spectroscopy relies on the principle that different types of chemical bonds absorb IR radiation at distinct frequencies. For instance, C-H, O-H, and N-H bonds exhibit characteristic absorption peaks within the infrared region of the electromagnetic spectrum. By analyzing the position and intensity of these absorption peaks, researchers can determine the functional groups present in a molecule and gain insights into its structure.

The instrumentation used for IR spectroscopy typically consists of an IR source, a sample holder, a detector, and a spectrometer. The IR source emits a beam of infrared radiation that passes through the sample. Molecules in the sample absorb specific frequencies of IR radiation, leading to changes in their vibrational energy levels. These changes are detected by the detector and processed by the spectrometer to generate the IR spectrum.

Applications of IR spectroscopy are diverse, ranging from identifying unknown compounds to monitoring chemical reactions. It plays a crucial role in fields such as organic chemistry, pharmaceuticals, materials science, and environmental analysis.
