【Abstract】 The EI, CI, DCI and FAB MS of β-carboxethyl germanium trichloride have been studied. From the results it can be seen that the Ge-Cl is the most active bond, so the fragments occur here easily. FAB MS for the compounds is very diagnostic because they react with matrices, glycerol and thioglycercl, to form new bonds of Ge-O and Ge-S instead of Ge-Cl bonds.更多还原
