摘要
本文报道簇合物的快原子轰击质谱研究,提出了标题簇合物的可能断裂途径。实验中观察到几个质量相差16u相当于簇合物一个被取代的新离子峰(其中X=0~3)、及,还观察到比分子离子峰高16u的m/z1219(3%)新离子峰。这些表明在质谱过程中有氧介入。此外。
The fast atom bombardment mass spectra (FABMS)of trinuclear cobalt cluster are reported. In the light of the spectra the fragmentation pathways are proposed,and several novel ion fragments are observed,which posses 16 atom mass units small than that from normal unimolecular decomposition reaction, exactly corresponding to the result of replacement of a sulfur atom by an oxygen atom in and [Co2 (C6H4S2)2]. In addition there is also an ion peak of 16 atom mass units larger than m/z 1219 (3% ) corresponding to It is interested for the posibility of new mode of reaction,and simply implies that the sample is sensitive to oxygen.
