有机磷化合物的质谱研究（XⅢ）．1，3，2－二氮磷杂环戊酮－（4）衍生物的电子轰击质谱

A Study on Alkali Metal Adduct Ions of Crown Ether Compound in Fast Atom Bombardment Mass Spectrometry

本文报道９种新的含磷杂环化合物的电子轰击质谱（ＥＩＭＳ），并应用Ｂ／Ｅ、Ｂ２／Ｅ联动扫描及精确质量测量技术，探讨了该类化合物的质谱断裂机理，发现骨架重排及开环反应是该类化合物主要的质谱特征，而Ｒ２基因对重排过程有很大影响。

Fast Atom Bombardment Mass Spectra(FABMS) of four crown ether compounds 1￣4 and K+, Na+ forming adducting ions have been studied. For these adducting ions, in their FABMS, [M+K]+and [M+Na]+are intense,and may give the information about molecurlar weight exactly.
