-Fe（CO）_3C_60 ~++2CO（2）显然是由动力学或内激发的C_60 ~+产生的，当Cm ~+经受1-s冷却时间时完全不存在。为了比较，对于Cr（CO）6没有观察到反应，可能是由于空间或电子原因。Fe-（CO）4C 60+的CID 21· 22（19-92 eV，实验室框架）导致羰基的连续损失，最终产生FeC 60+。CID能量（114-185 eV）的进一步增加仅给出Cm-1，这与我们先前的研究一致。9这些结果表明Z）（Fe+-C_（60））> D-（Fe+-CO）= 36.6±1.8 kcal/mol，23这也与我们以前的研究结果一致。9
—Fe (CO) 3C60++ 2CO(2) apparently results from kinetically or internally excited C60+ and is completely absent when the Cm+ is subjected to the 1-s cooling period. For comparison, no reaction is observed for Cr (CO) 6, possibly due to steric or electronic reasons. CID21· 22 of Fe-(CO) 4C60+(19-92 eV, lab frame) resulted in the consecutive loss of carbonyls to eventually yield FeC60+. A further increase in CID energy (114-185 eV) gives Cm" 1" exclusively, consistent with our earlier study. 9 These resultsindicate that Z)(Fe+-C60)> D-(Fe+-CO)= 36.6±1.8 kcal/mol, 23 which is alsoconsistent with our previous findings. 9
