• 最佳库匹配: 2,2,3,3-Tetrafluoropropan-1-ol #65316

• 未观察到C–F伸缩（1000–1400 cm⁻¹）的特征谱带，使得顶部谱库命中（2,2,3,3‑四氟丙‑1‑醇）在化学上不太可能。
• 预期在1720 cm⁻¹附近的强酯羰基吸收（常规甲基丙烯酸酯聚合物的关键标志）在显著峰集中缺失，对简单的甲基丙烯酸酯均聚物鉴定构成挑战。
• 没有额外的光谱数据，芳香族、甲基丙烯酸酯、醚和硅氧烷组分之间的确切平衡仍无法确定。

推荐的后续步骤: Acquire the full FTIR spectrum over 4000–400 cm⁻¹, particularly the 1800–1650 cm⁻¹ (carbonyl) and 1400–600 cm⁻¹ (C–F, aromatic C–H, Si–O) regions, to confirm or rule out carbonyl, aromatic ring, and halogenated species. Compare the spectrum with reference spectra of known methacrylate polymers, fluorinated alcohols, and siloxane‑containing copolymers to resolve the ambiguity. If possible, perform complementary analysis (e.g., Raman spectroscopy, NMR, or XPS) to identify the presence of fluorine, silicon, or specific functional groups.
