Abstract
Fragmentation mechanisms of hexamethyldigermane and hexamethyldisilane ions have been investigated using the collision-induced dissociation-mass spectrometry/mass spectrometry (CID-MS/MS) and ab initio MO calculations. The results of CID-MS/MS spectra showed that the [(CH3)3GeGe(CH3)3]+ ion was fragmented to be (CH3)3Ge+, followed by the secondary fragmentation generating CH3Ge+. The results of ab initio calculations showed that a C2H4 elimination occurred more easily than a C2H6 elimination from (CH3)3Ge+ in the low energy region.
