目前的FTIR证据不支持确凿的化合物级归属。虽然最近的谱库命中是(Z)-2-辛烯,但匹配质量实际上为零,并且没有直接或相关的文献证据独立支持该身份。观察到的光谱更安全地描述为脂肪族烃,显示出强烈的C-H伸缩和弯曲特征,弱带在3009 cm-1附近提示可能存在烯烃贡献。
推荐的后续步骤: Reacquire the FTIR spectrum with full fingerprint-region coverage and improved signal-to-noise, especially across about 650-1800 cm-1. Check specifically for an alkene C=C stretching band near 1640-1680 cm-1 to verify whether unsaturation is truly present. Compare the sample against authentic spectra of simple alkenes and alkanes, including octene and heptene isomers, rather than relying on the current low-match library result. If available, confirm with GC-MS, which is well suited to distinguishing small volatile hydrocarbons and positional isomers.
