本文报道66个新型含氟液晶类化台物的电子轰击电离质谱(EIMS)。66个化台物分为三个类型,即炔醚类、炔酯类和炔类.并利用MS/MS联用技术和高分辨质谱(HRMS)数据研究了三种不同类型化合物的裂解机理,并总结其觇律性,结果将有助于未知的类似化合物的结构鉴定。
This paper reports the electron impact ionization mass spectrometry (EIMS) of 66 novel fluorine-containing liquid crystal compounds. Sixty-six compounds are classified into three classes: acetylenic ethers, acetylenes and acetylenics, and the cleavage mechanism of three different types of compounds has been studied using MS / MS and HRMS data. And summarizes its regularity, the result will contribute to the structural identification of unknown analogous compounds.
