• 最佳庫匹配: 檫樹油 #151435

• 2071 cm⁻¹處的弱譜帶在氧化有機混合物的背景下缺乏明確歸屬，可能來自微量污染物、吸附的C-O或異常官能團。
• 典型檫樹油（主要為C、H、O）不預期有N–H基團（3420 cm⁻¹，[2]）的直接文獻支持，這表明可能存在胺/醯胺雜質或錯誤歸屬。
• 1646 cm⁻¹處的峰也可解釋為水的O–H彎曲，而寬廣的3420 cm⁻¹譜帶可能由水份主導，掩蓋了更具體的結構信息。
• 現有證據無法驗證明確的標誌譜帶（如C–Cl、C≡N、強羰基模式），因此確切的化學性質仍未解決。

建議的下一步: Perform gas chromatography–mass spectrometry (GC‑MS) to identify volatile organic constituents and confirm or refute the presence of sassafras oil components such as safrole. Obtain a reference FTIR spectrum of authentic Sassafras oil for direct comparison under identical measurement conditions. Use complementary techniques such as Raman spectroscopy or NMR to resolve the ambiguity between alkene unsaturation, carbonyl groups, and moisture contributions.
