核磁谱图求助,多谢大家?感觉既然是离子液体系是否这个碳的氧 会与乙酸作用? ? 因此羰基有可能变为 碳氧单键? 这样与位移是比较相符的 QQ截图20130108133911.png(55.77KB)http://kuai.xunlei.com/d/LnU4DU37CBPsUAQAad3?p=130497另外这是红外谱图在1653 cm-1 and 1281 cm-1, which could attribute to ν(C=O) and ν(C–O) stretching vibration of the acetate carboxylate at C(2) position of imidazolium rings. 另外乙酸的两个峰 the absorption peaks of the acetate carboxylate (C=O and C–O) were at about 1578 cm-1 and 1408 cm-1, 不知这样扥西对不,请指教,查看更多
