FTIR 搜索不支持對該樣品進行明確的化合物級別鑑定。最近的譜庫條目是 2-methyl-3-oxo-3-phenylpropanenitrile,但匹配信度實際上不存在,因此該名稱僅應視為頂部譜庫命中,而非確認的歸屬。觀察到的光譜更安全地描述為含有強羰基譜帶的芳香族有機材料,並具有與含 C-O 官能團和取代芳香環振動一致的附加指紋區譜帶。
建議的下一步: Inspect the full spectrum, especially 3600-2500 cm-1 and 2300-2100 cm-1, to check for O-H and nitrile bands that would strongly refine the assignment. Compare the sample directly against reference spectra for aromatic esters, aromatic ketones, and aromatic carbonate-containing materials, since these are more consistent with the observed carbonyl and C-O pattern than the nominal top hit alone. If available, run complementary GC-MS or LC-MS for a small-molecule sample, or Raman/ATR-FTIR comparison against known polymer/additive standards if the sample is from a formulated material. Verify whether the paired 1724/1698 cm-1 feature persists across repeat measurements; if S-O, consider the possibility of multiple components or conjugated carbonyl environments.
