- 2071 cm⁻¹处的弱谱带在含氧有机混合物背景下缺乏明确归属,可能源于微量污染物、吸附的C-O或异常官能团。
- 典型的檫木油(主要含C、H、O)不会直接有文献支持N–H基团(3420 cm⁻¹,[2]),这表明可能存在胺/酰胺杂质或归属错误。
- 1646 cm⁻¹处的峰也可以解释为水的O–H弯曲,而宽的3420 cm⁻¹谱带可能由水分主导,掩盖了更具体的结构信息。
- 目前的证据无法验证明确的标记谱带(如C–Cl、C≡N、强羰基模式),从而无法确定确切的化学性质。
推荐的后续步骤:
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.
