目前的FTIR證據不支持確定的化合物層級歸屬。雖然最近的譜庫匹配是(Z)-Oct-2-ene,但匹配品質實際上為零,且沒有直接或相關的文獻證據獨立支持該身份。觀測到的光譜更安全地描述為具有強C-H伸縮和彎曲特徵的脂肪族烴,並由3009 cm-1的弱譜帶提示可能的烯烴貢獻。
建議的下一步: 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.
