The singly charged fragments derive from the loss of H+ from the metalated product ions and the formation of a protonated complementary product ion; such observations are similar to previous reports for magnesium and calcium salts undergoing electron capture dissociation (ECD) activation. However, during He-CTD, the [M + Mg]2+ precursor generated more singly charged product ions than [M + Ca]2+ , either because Mg has a higher second ionization potential than Ca or because of conformational differences and the locat
