FTIR谱图与脂肪族酯类有机物质最为一致,而非对谱库匹配结果24937-78-8的确定识别。样品在1737 cm-1处显示强羰基谱带,同时在2916和2849 cm-1处有脂肪族C-H伸缩,1467和1370 cm-1处有CH弯曲,以及近1237 cm-1处有一条与酯中C-O伸缩相符的谱带。719 cm-1谱带支持延伸的亚甲基链或有序长链烃特征。尽管谱库返回24937-78-8作为最近匹配,但检索置信度实际上为零,且没有直接或相关的文献证据独立支持该特定分配。
推荐的后续步骤: Reacquire the FTIR spectrum with full fingerprint-region quality and report relative band intensities, especially from about 1800 to 650 cm-1. Check specifically for additional ester C-O bands in the 1300-1000 cm-1 region and for any broad O-H or distinct N-H stretching bands to confirm or exclude alternative functionalities. Compare the sample against reference spectra of long-chain aliphatic esters, wax esters, fatty acid esters, and common plasticizer-type esters. If exact identification is needed, confirm by GC-MS or LC-MS for molecular composition, or by NMR if the sample is sufficiently pure.
