- 與檫木油的譜庫匹配與強醯胺 I 和硫氰酸根譜帶的存在相矛盾,這些在簡單精油中不應出現;最近的譜庫命中可能是整體光譜相似性而非化學身份的假象。
- 無法確定精確組成;混合物可能含有蛋白質、無機氧化物 (矽石、金屬氫氧化物) 和硫氰酸根,但各成分的相對比例和具體身份仍不清楚。
- 764 cm⁻¹ 的譜帶以中等信心歸屬於芳香族 C–H 彎曲;不能完全排除其他歸屬,如甲基搖擺 (χ(CH₃OH))。
- 樣品可能是多組分廢物、生物殘留物或降解的複合材料;需要進一步分離或補充分析。
建議的下一步:
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).
