摘要
本文讨论了2M—4MPA和2M—4H—3MPA的质谱及裂解途径。分析了影响碎片离子丰度的因素,为该类化合物的结构分析提供了质谱参考。
In this paper, We have discussed the mass spectrum of the 2M—4MPA and 2M—4H—3MPA and their fragmentation process. We also have analysed the factor of the influence on the abundance of fragment ion. The results provide a reference fundation for the analysis of structure of these kinds of compounds in the future
