Figures

Figure 1
The ETD and AI-ETD spectra of RPKPQQFFGLM (A/B) and ACTH (C/D) generated via 100 ms reaction with radical azobenzene anions. For AI-ETD, laser power was 99%.

Figure 2
The isotopic distributions of the z₆^• and c₈ product ions for ETD (A), AI-ETD (B), ETirD (C), and ETcaD (D) generated from a 100 ms reaction with radical azobenzene. For AI-ETD and ETirD laser power was set at 99%. Closed circles denote the theoretical distribution of typical ETD product ions.
