Figure 3. IRMPD of the small peptide MRFA across laser powers.
Dissociation of the singly protonated peptide MRFA (m/z = 524.26) tracked as a function of precursor decay, where A0 is the precursor intensity before irradiation and A is the precursor intensity after a given reaction duration. Each point represents an average of ten transients after photoirradiation via the designated power level (corresponding to ~ 26, 32, 38, 44, and 50 W laser output, from top-to-bottom, respectively). Curves represent an exponential decay asymptotic fit.
