IRMPD shows that NicGGOMe is protonated at the pyridine ring of the nicotinyl group, and more importantly, that b(2)(+) from NicGGOMe is not protonated at the oxazolone ring, as would be expected if the species were generated on the conventional b(n)(+)/y(n)(+) oxazolone pathway, but at the pyridine ring instead. IRMPD data support a hypothesis that formation of b(2)(+) from NicGGOMe involves mobilization and transfer of an amide position proton during the fragmentation reaction.
