Fig. 2. Example (CQ0)2– photoelectron spectra (black) and CQ0– (grey) from ref. 28 at three hν: (a) 4.66 eV; (b) 4.13 eV; (c) average between 2.53 eV and 3.02 eV. Included in (a) are the contributions from the three global-fit channels. The red bars in (c) are calculated carbonyl wagging modes localised on the non-planar monomer.
