H3+ formation from ethanol. Truncated coincidence time-of-flight maps focused only on H3+ production in two-body channels from dissociative ionization of a CH3CD2OD and b CD3CH2OH in a linearly polarized laser pulse centered about 790 nm, 23-fs long with a peak intensity of 3.0 × 1014 W cm−2. The labeled dashed lines indicate the two-body breakup ion pairs related to H3+ formation from the ethanol dication. The logarithmic color scale depicts the number of ion pairs recorded
