摘要： 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。

Abstract: In this paper, three pairs of dl and meso-diethyl-2,3-dicyano-2,3-diphenyl succinate and its derivatives of p-(X)substituted phenyl succinates(X=H,CH3,OCH3) were analyzed by using FAB-B/Elinked scan metastable ion spectrometry. The effect and applicability of this method in identification of the configuration of these isomers were discussed.

Key words: FAB-B/E link scan, Diethyl-2,3-dicyano-2,3-diphenyl succinates, dl and meso con-figuration
