該光譜與以亞甲基 C-H 振動為主的簡單脂肪族烴材料最為一致,其輪廓最接近聚乙烯類譜庫方向。然而,譜庫匹配品質非常弱,且無直接參考或相關文獻證據獨立確認具體聚合物等級或確切身份,因此最可支持的結論是較廣義的聚乙烯類富含亞甲基烴材料,而非明確的實體歸屬。
建議的下一步: 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.
