摘　　要：利用气相色谱-质谱联用仪(GC-MS)对2类共6种异硫氰酸酯(NCS)液晶化合物进行质谱分析(EI),总结了化合物的裂解规律.2类NCS液晶化合物裂解主要发生在苯环苄位烷基和与苯环相连的环己基上,并在此基础上有失去质量32和59的碎片峰.By analyzing two classes,total 6 isothiocyanate(NCS)liquid crystal compounds with GC-MS,this paper summarizd their molecules cracking discipline through mass spectrum interpretation.It was found that the cracking has a significant possibility occurring at benzcyclobenzyl alkyl and cycloalkyl which linked with benzene ring,and these basis losing mass are 32 and mass 59 fragments,respectively.
