摘要
本文报导了五种7—哌嗪喹诺酮类化合物的EI谱,并讨论了特征碎片离子的裂解规律。8-N-7—哌嗪喹诺酮化合物的m/z(M-68)可能来自3氢原子的重排的结果。
In this paper EI Mass Spectra of five 7-Piperazing Quinolones were measured. The fragmentations of characteristic fragment ions were discussed. The m/z(M-68) fragment ion of 8-N-7-Piperazine Quinolones probably results from a rearrangement of three hydrogens.
