## Abstract Chromophore effect in the photodissociation of protonated peptides at 266 nm was investigated using synthetic peptides with the sequence RGGXGGGGGR where X was a phenylalanyl(F), tyrosyl(Y), cysteinyl(C), glycyl(G), seryl(S), or histidyl(H) residue. The peptides with an F or Y residue d
