【摘要】 本文通过电子轰击（EI）质谱和亚稳跃迁测定,对N-2-苯乙烯基和取代N-2-苯乙烯基的一系列化合物的裂解过程进行了研究。全部11个化合物的质谱都给出了较强的分子离子峰,其中大部分为基峰。这类化合物易形成环状结构,不同于甲基或苯基取代的邻苯二酰胺的质谱,[M-CO₂]⁺离子峰没有或者很低。更多还原

【Abstract】 With electron ionization （EI） mass spectra and metastable ion measurement, a study of fragmentation of N-2-styrylphthalamide and its derivatives are described in this paper. All spectra from the eleven compounds of this series showed strong molecular ion peaks. Most of them were base peaks. In contrast to methyl or phcnyl substituted phthalamides, the （M-CO₂）⁺ ion peaks were absent or weak in these spectra.更多还原
