    • Unfortunately, the gas phase thermochemistry associated with the dissociation reactions of these complexes is unknown. Their solution phase electrochemistry is of limited value in making gas phase predictions on IPs, since they are dependent on both the solvent and the coordinating ligand.

    • note
    • The development of metal complexes of peptides as a bioanlytical tool hinges upon a number of condensed and gas phase factors. The ideal ternary metal complex would (i) readily form in the condensed phase, (ii) be sequence independent in its binding of peptides, (iii) readily transfer to the gas phase under ESI conditions without undergoing charge reduction or fragmentation, and (iv) fragment to give abundant peptide cation radicals. In our work we have solely focused on the gas phase fragmentation behavior of the ternary complexes and have not tried to optimize their condensed phase behavior. We note that, in general, Fe, Co, and Mn readily formed the ternary complexes in high abundance.

    • The subsequent fragmentation of the peptide cation radical may be a result of electronic excitation. Schlag and co-workers have demonstrated that tetrapeptides are characterized by many and densely spaced excited electronic states and that these provide opportunities for charge migration and fragmentation in peptides: Remacle, F.; Levine, R. D.; Schlag, E. W.; Weinkauf, R. J. Phys. Chem. A 1999, 103, 10149-10158.
