摘要
对手性苯基吡啶、苯基嘧啶类液晶共十九个化合物进行了电子轰击质谱和化学电离质谱测定，讨论了它们的质谱特征和裂解机理。
Liquid crystal compounds which include diphenylpyridine,diphenylpyrimidine derivatives are analysed with electron impact(EI)and chemical ionization(CI)mass spec-trometry.General fragmentation mechanism of these compounds and mass spectral behavior have been discussed in detail.
