Identification Result
93%The library search identifies the sample as 1H-1,2,4-Triazole (similarity 0.911, high confidence). The spectrum is dominated by vibrational modes characteristic of an aromatic nitrogen heterocycle. Aliphatic C–H bands and a weak carbonyl feature, however, suggest the presence of a minor hydrocarbon component or substitution 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.
Detailed interpretation
- Top library match: 1H-1,2,4-Triazole #20493
- Strong bands at 2840, 2867, 2930, and 2969 cm⁻¹ are characteristic of aliphatic C–H stretching, which is not part of the unsubstituted triazole structure. Their presence indicates a hydrocarbon contaminant or a minor alkyl-substituted analogue.
- The origin of the carbonyl band at 1766 cm⁻¹ remains open; it could arise from a C-O‑eluting substance or partial oxidation. The aliphatic C–H stretching region also deviates from the pure library reference, S-O the sample may not be the neat compound.
