光谱与以亚甲基C-H振动为主的简单脂肪族烃材料最一致,最近谱库方向为聚乙烯类轮廓。然而,谱库匹配质量非常弱,没有直接参考或相关文献证据独立确认特定的聚合物等级或确切身份,因此最支持的结论是更广泛的聚乙烯类富含亚甲基的烃材料,而非确切的实体分配。
推荐的后续步骤: Collect a full FTIR spectrum including the fingerprint region to check for the characteristic polyethylene rocking doublet near 730-720 cm-1 and to assess branching-sensitive features. Inspect for any carbonyl absorption near 1700-1750 cm-1 to exclude long-chain esters or oxidized material suggested by some library candidates. Check for C-Cl region absorption in the lower wavenumber range if chlorinated polyethylene is a practical alternative to exclude. If polymer identification matters, compare against authenticated HDPE, LDPE, and generic polyethylene reference spectra measured under the same sampling conditions.
