The samples were dissolved in dimethyl sulfoxide (DMSO) and the data were recorded by positive ion mode. No any other fragment was found except for little molecular ion which loses a chlorine atom.
样品溶解在二甲基亚砜中,以正离子方式记录谱图,结果发现除产生一个失去氯原子的分子离子峰外,没有任何碎片峰。
The existence of carbonyl group in structure seems to be a factor that favors the formation of quasi-molecular ion (QMI) or other adduct molecular ion (OAMI) in positive mode.
化合物结构中羰基的存在似有利于化合物在正离子模式下形成准分子离子或其它分子加和离子。
