• 最佳库匹配: 檫木油 #151435

• 与檫木油的谱库匹配结果与强酰胺 I 和硫氰酸根谱带的存在相矛盾，这些谱带在简单的精油中是不期望的；最近的谱库命中可能是整体光谱相似性而非化学身份的假象。
• 无法确定精确组成；混合物可能含有蛋白质、无机氧化物（二氧化硅、金属氢氧化物）和硫氰酸根，但各组分的相对比例和具体身份仍不清楚。
• 764 cm⁻¹ 处的谱带以中等置信度被归属为芳香族 C–H 弯曲；其他归属如甲基摇摆 (χ(CH₃OH)) 不能完全排除。
• 样品可能是一种多组分废物、生物残留或降解的复合材料；需要进一步分离或补充分析。

推荐的后续步骤: Perform solvent extraction or chromatographic separation followed by FTIR or GC‑MS to isolate the organic components and confirm the presence of protein and thiocyanate. Employ X‑ray diffraction (XRD) or X‑ray fluorescence (XRF) to identify the crystalline inorganic phases suggested by the bands at 472 and 3853 cm‑1. Use thermogravimetric analysis (TGA) to estimate the organic/inorganic ratio and to verify the loss of water/hydroxyl at characteristic temperatures. If the sample history is unknown, consider elemental analysis (CHNS) to quantify nitrogen (from amide/thiocyanate) and sulfur (from thiocyanate).
