Novel Gas Phase Ion Molecule Reactions of C60++ with O2 and NH3
Abstract
We have recently utilized a tandem triple quadrupole mass spectrometer to probe the gas phase ion-molecule chemistry of C60++ with a variety of target gases, at low collision energies. We have observed a high degree of reactivity of C60++ with oxygen to produce C60+, C60O2+ and C60O+. Likewise, we have also observed reactivity of C60++ with ammonia to produce C60NH2+, C60NH2(NH3)+, C60NH2(NH3)2+ and C60NH2(NH3)3. We propose that the product ions result from an electron transfer reaction followed by covalent bond formation. All reactions were observed to be highly dependent on collision energy and target gas pressure. We believe that these processes are part of a larger family of charge exchange reactions for C60++ which occur for any molecule whose ionization potential lies below 12.25 eV, the first ionization potential of C60+.
