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。
The process of ion formation of thirteen title compounds in EIMS has been studied byusing low and high resolution and B/E B^2/E link scanning techniques. Discussion is focu-sed on the effects of substituents on abundances of molecular and fragment ions. The rela-tionship between 1gZ/Z_o and substitution constant σ is in good agreement with the Hammettfree energy equation 1gZ/Z_o = ρσ.
