摘　　要：本文首次报道了一系列顺,反-4-三甲(代)甲硅烷基环己醇类似物及其衍生物的电子轰击(EI)质谱。根据亚稳离子分析和精确质量测量数据推断了它们的碎裂规律。硅的原子结构特征和官能团的空间构型对其碎裂过程有明显的影响。其谱态可作为上述立体异构体的结构区分特征。In the present work the EI mass spectra of cis.trans-4-trimethylsilylcyclohexyl alcohol analogues and their derivatives have been reported firstly. The fragmentional pathways have been proposed on the basis of accurate mass measurement and metastable transition. The atomic structure of silicon and steric configurations of functional groups in the stereoisomers have a distinguished effect on their fragmentational behaviours. The spectral patterns can be used to characterize the above stereoisomers.
