UVPD spectra (10 pulses, 6 mJ) of a) PC 18:0/18:0 ([M+H]+, m/z 790.63), b) PC 18:0/18:1(9Z) ([M+H]+, m/z 788.61), and PC 18:0/18:2(9Z,12Z) ([M+H]+, m/z 786.60). d) Bar graph comparing the impact of the number of double bonds on HCD and UVPD as a function of precursor depletion measured as the percentage of surviving precursor after activation.
