摘要： 本文应用低分辨及高分辨EI质谱,亚稳分析,研究了13个标题化合物的质谱断裂机理和主要离子的形成过程,着重讨论了取代基对分子离子及碎片离子强度的影响。
关键词: EI质谱, 低分辨, 高分辨, B/E和B2/E联动扫描, 对甲苯磺酰胺基乙酰胺, 取代基效应
Abstract: The process of ion formation of thirteen title compounds in EIMS has been studied byusing low and high resolution and B/E B2/E link scanning techniques.Discussion is focu-sed on the effects of substituents on abundances of molecular and fragment ions.The rela-tionship between lgZ/Zo and substitution constant σ is in good agreement with the Hammettfree energy equation lgZ/Zo = ρσ.
Key words: high resolution low resolution, EI mass spectrometry, B/E and B2/E link scanning, rearrangement reaction, p-tolylsulfonamide acetamide, substiution effect
