FTIR搜索不支持对该样品的明确化合物级别鉴定。最近的谱库条目为2-甲基-3-氧代-3-苯基丙腈,但匹配置信度实际上不存在,因此该名称仅应视为最佳谱库匹配,而非确认的鉴定结果。观察到的光谱更可靠地描述为含有强羰基谱带的芳香族有机材料,并伴有与含C-O官能团和取代芳香环振动一致的额外指纹区谱带。
推荐的后续步骤: 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.
