摘要
利用氣相色譜-質譜聯用儀(GC-MS)對2類共6種異硫氰酸酯(NCS)液晶化合物進行質譜分析(EI),總結了化合物的裂解規律.2類NCS液晶化合物裂解主要發生在苯環芐位烷基和與苯環相連的環己基上,并在此基礎上有失去質量32和59的碎片峰.

Abstract:
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.
