H3+ production from a series of alcohols. Total H3+ branching ratios ([Σx(H3+ + mx+)]/[all dication products]) together with normalized H3+ ([H3+]), and fractional H3+ ([H3+]/[all ions]) production from dissociative ionization of methanol, ethanol, 1-propanol, and 2-propanol together with tert-butanol in a linearly polarized laser field with a peak intensity of 2.0 × 1014 W cm−2. The [H3+] and [H3+]/[all ions] yields were obtained through the TOF technique, and each of them is normalized with respect to the corresponding branching ratio of methanol, [(H3+ + HCO+)]/[all dication products], determined by the CTOF method. Due to the complexity of quantitative analysis (see text for details), CTOF measurements were not performed for large molecules (2-propanol and tert-butanol) and indicated by “NA” at the corresponding positions in the figure. Data are provided as Supplementary Table 1
