用低分辨电子轰击源质谱、高分辨精确质量测量质谱法研究了dl-2,3-二氰基-2,3-二(P-X取代苯基)丁二酸二乙酯(x=OCH_3、CH_3、H、Cl、NO_2)的质谱。讨论了这类化合物的质谱裂解机理及特征离子的结构。
The effects of dl-2,3-dicyano-2,3-di (PX substituted phenyl) succinic acid diethyl ester (x = OCH_3, CH_3 , H, Cl, NO 2). The mass spectroscopic cleavage mechanism of these compounds and the structure of the characteristic ions were discussed.
