FTIR圖譜支持寬泛歸屬於含有明顯脂肪烴成分、強羰基成分以及與N-H和/或C-O鍵一致的附加極性官能團的有機材料。此處譜庫頂級匹配在化學上不可靠,因為所有報告的譜庫相似度均為0.000,且無直接或相關文獻證據縮小身份。觀察到的譜帶更符合混合或廣泛功能化的有機材料,而非特定的命名譜庫化合物。
建議的下一步: Verify whether the 3341 cm-1 feature is N-H or O-H by checking band shape and by collecting a higher-quality spectrum with good baseline correction. Inspect the 1800-1500 cm-1 region for secondary carbonyl-related or amide-related bands to distinguish ester, ketone, acid, or amide character. Acquire complementary Raman or GC-MS/LC-MS data if the sample is molecular and extractable, since the current FTIR evidence is too weak for compound-level identification. If this is a formulated or unknown residue sample, compare against reference spectra of carbonyl-containing organic materials such as ester-containing organics, amide-containing organics, or mixed hydrocarbon/polar additives.
