FTIR谱图与含氧酯类材料最为一致,可能是聚合或低聚物种而非简单烃类。最有力的样品证据是1708和1725 cm-1处的羰基区域,以及1055、1098、1165、1178、1240和1285 cm-1处的多个C-O伸缩谱带,加上2935 cm-1处的脂肪族C-H和3373 cm-1附近的宽O-H/N-H区域。谱库最高命中是聚己内酯单羟基封端,更广泛的顶级候选模式由含氧酯类聚合物主导,如甲基丙烯酸羟乙酯和聚酯型材料。然而,谱库匹配质量非常弱,并且没有直接或相关的文献证据独立确认特定的命名聚合物。因此,最可支持的结论是更广泛的含氧酯聚合物或低聚物方向,可能带有羟基封端,而非确定归属为聚己内酯单羟基封端。
推荐的后续步骤: Compare the full spectrum directly against authenticated FTIR references for Poly(caprolactone),monohydroxy terminated, poly(2-hydroxyethyl methacrylate), and common aliphatic polyesters such as poly(trimethylene succinate). Check for polyester-specific thermal behavior by DSC; a melting transition near the expected range for semicrystalline aliphatic polyester would help separate polycaprolactone-like material from methacrylate-based materials. Use 1H and 13C NMR to verify whether the sample contains caprolactone-type methylene environments, methacrylate backbone features, or mixed ester components. If the 3373 cm-1 band is important to the assignment, dry the sample and reacquire FTIR to determine whether the band persists as a true hydroxyl feature rather than adsorbed moisture.
