The IT MS2 spectra of the [M – H]− ions of 19:0/16:0-PI at m/z 851 (a) and of the ion at m/z 849 (b), which consists of two major 18:1/17:0-PI and 19:1/16:0-PI isomers, along with a minor 19:0/16:1-PI structure. Panel (c) shows the IT MS2 spectrum of the [M – H]− ion of 19:0/16:0-PIM1 at m/z 1013, which contains the ions analogous to those arising from 19:0/16:0-PI (a).
