Infrared characteristic peak of adipic acid

There are several significant characteristic absorption peaks in the infrared spectrum of adipic acid, which are crucial for identifying adipic acid and its derivatives. In infrared spectroscopy analysis, specific functional groups in adipic acid molecules absorb specific wavelengths of infrared light, producing characteristic absorption peaks.
Among them, the most obvious characteristic peaks are located at 1750cm-1 and 1710cm-1, which correspond to the C=O stretching vibration and C-O bending vibration in the carboxyl group, respectively. These vibration modes reflect the structure and vibration characteristics of carboxyl groups in adipic acid molecules.
By observing and comparing the positions, shapes, and intensities of these characteristic absorption peaks, adipic acid molecules can be accurately identified and distinguished from other organic compounds. Therefore, infrared spectroscopy analysis is a very effective chemical analysis method widely used in the identification and structural analysis of organic compounds.
