The FTIR spectrum is indicative of a phosphorus-containing organic material, likely comprising a phosphite or phosphate ester backbone, in combination with aromatic and methacrylate functional groups. The presence of a strong band near 1007 cm⁻¹ suggests a phosphorus‑oxygen stretching vibration, while bands in the 600–900 cm⁻¹ region are consistent with aromatic out‑of‑plane C–H deformations. A carbonyl‑related absorption at 1417 cm⁻¹ and a prominent O–H stretch at 3709 cm⁻¹ further point to an organic ester or carboxylic acid component, potentially methacrylate‑derived 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.
