The spectrum is consistent with a nitroaromatic compound bearing carbonyl groups, as suggested by reference library comparison (nearest match 1-(4-nitrophenyl)pyrrole-2,5-dione). Key features include a split carbonyl doublet at 1724/1740 cm⁻¹, a para‑substituted aromatic pattern at 724/747 cm⁻¹, and aromatic ring vibrations at 1550/1613 cm⁻¹. The exact identity remains uncertain due to moderate library similarity and conflicting inorganic assignments in the direct evidence
