Channel yield versus time. Normalized yield as a function of time for the time-dependent features for the a NHM (green, 0–4 eV KER), SHM (red, 0.5–3.6 eV KER), and DHM (blue, 0.5–3.6 eV KER) double coincidence channels and b the triple coincidence channel H⁺ + H₂O⁺ + C₂H₃⁺, split into 0–5 eV KER (blue), 5–13 eV KER, inner arch (red), and 5–13 eV KER, outer arch (purple). Experimental error bars are statistical. Theory (solid lines) is carried out for the cation with 10 eV internal energy in (a) and the dication with 5 eV internal energy in (b)
