摘要
Energy raolved mass spectra (ERMS) of 2, 3-DNT and 3, 5-DNT isomers was mported. The fragmentation of this pair of DNTisomers was studied by ERMS in electron impact (EI),and their breakdown curves were discussed , These nitraromaic isomers can be characterized according to the differences between their ERMS in MS/MS
用能量分辨质谱(ERMS)来鉴别质谱分析中的同分异构体化合物,系统探讨了同分异构的硝基芳香化合物2,3-DNT和3,5-DNT(分子量为182)在电子轰击(EI)方式下,裂分途径与其分子内能的相互关系以及离子的结构和裂分途径相对于碰撞能量(CE)的依赖关系(裂分曲线).结果表明,利用同分异构化合物在能量分辨中的显著差异可以辨别它们的结构。
