الملخص	Infrared (IR) spectroscopy measures the absorption of infrared radiation by chemical bonds, creating a spectrum unique to each compound. Discovered by William Herschel in 1800 and developed into a practical analytical tool in the mid-20th century, IR spectroscopy is indispensable for rapidly identifying functional groups and confirming compound structure in organic and inorganic chemistry.	Functional group identification is the systematic determination of chemical functional groups present in organic molecules using spectroscopic, chemical, and structural data. Developed throughout the 20th century alongside spectroscopy and analytical chemistry, this methodology enables rapid structure elucidation by focusing on reactive moieties (alcohols, aldehydes, carboxylic acids, amines, etc.) rather than complete structure determination.
