Difference between Experimental IR and literature IR of pure salicylic acid

Explanation on the different regions found on an IR spectrum (diagnostic vs fingerprint)
- Explanation on how chemical effects (for example, the conjugation of C=O with C=C double bond) alter peak regions.
- Comparison of specific functional group diagnostic peaks (C=O carboxylic acid, C-H, O-H carboxylic acid, O-H phenol, C=C) between Literature and Experimental spectra.
- Comparison of fingerprint region between literature and experimental spectra.

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
