The FTIR spectrum is consistent with an organic substance that contains carboxylate or carboxylic acid groups and amide linkages, likely incorporating aromatic or alkene unsaturation. The reference library comparison matches point to a broad aromatic/alkene class at low confidence, and the spectral patterns align with those of organic acids, amides, and potentially aromatic or conjugated systems FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
