质谱技术用于区分异构体已有不少有意义的工作,Beynon等利用亚稳离子谱鉴别异构体,提出离子动能谱具有化合物独特的“指纹”作用,是鉴别EI谱图相似的同分异构体的有效方法,苏克曼等用EI-B/E联动扫描技术研究了常规EI谱极为相似的二元取代苯位置异构体的谱图,讨论了用EI-B/E联动扫描亚稳离子谱鉴别二元取代苯位置异构体的作用,上 Mass spectrometry techniques have been used to distinguish isomers have a lot of meaningful work, Beynon and other use of metastable ion identification of isomers, proposed ion kinetic energy spectrum has a unique compound “fingerprint” is to identify similar EI spectrum The effective method of the isomers, Sukman and other EI-B / E linkage scanning technique to study the conventional EI spectrum is very similar to the binary substituted benzene position isomers spectrum, discussed the use of EI-B / E linkage Scanning metastable ion spectra identify the role of the binary substituted benzene positional isomer, supra
