摘要

Dissociation of the peptide bond in protonated peptides proceeds via proton-bound complexes between the emerging N- and C-terminal fragments. At least two interconverting complexes are involved, one leading to b-ions (mostly protonated oxazolones) and linear peptides and the other entailing y-ions (protonated linear peptides) and neutral cyclopeptides. Without reverse activation energies, the relative gas-phase basicities of the fragments and the energetics of the accompanying neutrals determine the ratio b- to y-ions.
