Impact of resonant excitation parameters on the intra-complex gas phase HDX within small non-covalent systems

Résumé

Objective Exploring unexpected H/D exchanges between the partners of small sodiated noncovalent complex (NCC) anions constituted by fructose 6-phosphate (F6P) and arginine (R) for distinguishing between their solvated salt (SS) and hydrogen bonded (HB) forms. Main observations Complementary enrichment(+D)/depletion(-D) detected in diagnostic product ions related to each partner favored under resonant excitation conditions by increasing excitation parameter values (ExcTime, ExcQ and NCE). Suggested stepwise process involving hydride/deuteride transfer from specific carbon atom to another (e.g. nitrogen) atom within SS form of NCC rather than proton/deuteron exchanges.
