【摘要】 本文首次报道Ln（OOCCF₃）₃(Ln=Pr、Nd、Sm、Eu、Gd、Tb、Ho、Er、Tm、Yb、Lu在甘油（G）中的正负离子FAB谱、总结了其离子特征。通过亚稳分析、探讨了某些离子的碎裂方式,提出了Ln（Ⅱ）→Ln（Ⅰ）可能的还原变价机制。更多还原

【Abstract】 This paper reported the positive and negative ion fast atom bombardment mass spectra of rare earth-trifluoroacetic acid complexs Ln（OOCCF₃）₃ （Ln=Pr, Nd, Sin, Eu, Gd, Tb, Ho, Er, Tm, Yb, Lu） in the matrix glycerol. The ionic characteristics have been submitted and discussed. The fragmentation and formation of several ions have been investigated and the reduction mechanism of Ln（Ⅲ）——Ln（Ⅰ）has been suggested by analyzing the corresponding daughter or parent ions.更多还原
