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．
The mass spectra of 29 bonded double azoles were tested and their mass spectrometric cleavage processes were studied using metastable ionization. The results show that most of the above compounds are split from the azole ring. Methyl readily participates in rearrangement when the methyl group is adjacent to the azole ring, and it is found that these compounds are easy to form double-charged molecular ions. The larger the conjugated system, the higher the intensity of the double-charged molecular ion peak.
