A step by step demonstration of radical generation via UVPD of an electrostatic complex: (a) UVPD of the electrostatic complex between RARARAA (denoted as M) and MIBS, (b) CID of the resulting iodine loss product and (c) CID of the radical peptide. (d) CID of the even electron [M+H]+ is provided for comparison. (e) The C-I bond cleavage via UVPD of MIBS is provided. The lightning bolt image indicates the precursor ion for each CID experiment. The star symbol indicates the precursor ion for the UVPD experiment.
