Applications for infrared spectroscopy (IR) include identifying chemical species, determining chemical species quantitatively or qualitatively, and determining molecular structure.
Investigations of matter in its solid, liquid, and gaseous phases use this technique. Specific functional groups in polymers can be sensitively detected using infrared spectroscopy (IR). Functional groups like hydroxy, amine, and carbonyl can be quickly identified by IR, especially when working with hydrocarbon polymers like polystyrenes and polydienes.
Chemists employ it to identify functional groups in compounds. By measuring atom vibrations using IR spectroscopy, the functional groups of molecules can be identified. 5 Stronger links and light atoms will often vibrate at a high stretching frequency.
