摘要
本文报导了若干双—(环戊二烯基)取代苯甲酸锆氯化物的质谱,并基于第一无场区的亚稳离子的测定和同位素丰度分布的分析提出了它们单分子离子的主要断裂途径,并发现它们的某些碎片离子的断裂行为与苯甲酸根配体上取代基的负电性存在着明显的相关。
The mass spectra of some bis-cyclopentadienyl substituted benzoatozirconiumchlorides have been reported and their main fragmentation pathways have been proposed on the basis of the linked scan information of metastable transition in first field-free region and analysis the abundance distribution of the isotopic peaks. It is found that the cleavage behaviour of their some fragment ions closely -relate to the electronegativity of the substituents in aromatic ring.
