Aromatic/alkene-rich organic mixture with carbonyl, carboxylate/amide and hydroxyl functionality (humic-like/proteinaceous material)
Sample & Measurement Parameters
Identification Result
29%The spectrum is best explained as an aromatic/alkene-rich organic material containing significant oxygen and nitrogen functional groups — carbonyl, carboxylate/amide, and hydroxyl. The band pattern, notably the 1629 cm–1 (amide I/carbonyl/aromatic C=C) and the 1384/1399 cm–1 carboxylate pair, strongly resembles humic-like substances or proteinaceous organic matter. The library’s top single-match ‘azane; formic acid’ is chemically inconsistent with this aromatic/carbonyl evidence, indicating the true sample is a complex mixture rather than a neat compound 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.
