| 摘 要： | 测试了２９种键联双唑类化合物的质谱，利用亚稳离子技术研究了其质谱裂分过程．结果表明，上述化合物大多裂分过程都是先从唑环开始的．唑环邻位有甲基时，甲基易参与重排，并且发现该类化合物易形成双电荷分子离子，共轭体系越大，双电荷分子离子峰的强度越高．

| Abstract: | The mass spectra of twenty-nine bond-linked bisoxazoles were measured. The fragmentation pathways were studied by the metastable ion technique. The results show that most of the fragmentation reactions begin at oxazole rings and the methyl group will take part in the fragmentation rearrangement when it is in the o-position of the oxazole ring. We also found that double-charge molecular ions form easily among these compounds. The larger the conjugationsystem is, the higher the double-charge molecular ion peak is. |
