Alkali Metal Adduct Radical Cations of Cysteine Derivatives: A Gas-Phase Reactivity and Structural Elucidation Study

摘要

IMRs suggest radical migration to the α-carbon does not occur in [M+Cys]~(·+) but does occur in [M+Hcy]~(·+). IRMPD of [M+Cys]~(·+) corresponds to sulfur-based radical cation structures.
