| 摘 要： | 对一些恶嗪酮并苯并硫氮杂Ｚｈｕ衍生物在ＦＡＢ和ＣＩ条件下的ＲＤＡ碎裂反应进行了比较研究。在ＦＡＢ条件下，产物离子与质子分子ＭＨ＾＋的强度比明显低于ＣＩ。结果表明，ＦＡＢ质子化机理与ＣＩ是不同的。本文对ＦＡＢ质子化理进行了探讨。

| Abstract: | The comparative study was carried out on RDA fragmentation of some derivatives of oxazinono benzothiazepine under FAB and CI. It was found that the intensity ratio of product ions to protonated ion MH + under FAB were significantly lower than that under CI. It was shown that the mechanism of protonation under FAB was quite different from that under CI. A proposal mechanism of protonation under FAB was discussed. |
