Identification Result
29%The infrared spectrum is typical of a saturated polyester or a similar ester‑based material. A strong carbonyl band at 1732 cm⁻¹, aliphatic C–H stretching at 2934 and 2873 cm⁻¹, prominent C–O bands in the 1082–1140 cm⁻¹ region, and a broad O–H feature near 3536 cm⁻¹ collectively point to an ester backbone with aliphatic chains and some hydroxyl character 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.
