摘要
Abstract
The EI mass spectra of two kinds of liquid crystals alkylcyclohexylbenzene derivatives and alkylcyclohexylbiphenyl derivatives were analyzed with the gas chromatogram/mass spectrometer, and the fragmentation rules of them were summarized in this paper.The EI mass spectra in analogy with the Alkylcyclohexylbenzene derivatives and alkylcyclohexylbiphenyl derivatives,abundant mo-lecular ions are presented in all the spectra.They have three most characteristic ions,the odd electron ions at m/z100+R2 +R3 +R4 +R5 [m/z 175+R2 + R3 +R4 +R5 +R6 ]and their satellites the even e-lectron ions at m/z 87+R2 +R3 +R4 +R5 and m/z 1 13 +R2 +R3 +R4 +R5 [m/z 1 62 +R2 +R3 +R4 +R5 +R6 、m/z 188+R2 +R3 +R4 +R5 +R6 ]in the mass spectra.关键词
