Ultraviolet Photodissociation of Peptides: New Insight on the Mobile Proton Model

Aleksandr Pereverzev, Elizaveta Solovyeva

In this work, we study the mechanism of peptide photodissociation by ultraviolet irradiation at 193 nm wavelength and discuss the role of ionization proton in this process. We found that substituting the ionization proton for the alkali metal cations (sodi ...
