Experimental and theoretical data on total ionization cross sections for electron scattering by 1-butanol molecules in the energy range 10–100 eV are reported in this work. The experimental data were obtained from the addition of partial ionization cross sections (PICS) of 38 cationic fragments registered using a Hiden Analytical quadrupole mass spectrometer (EPIC 300), which are reported in a companion paper (Pires et al., 2018). The theoretical data were generated using the Binary-Encounter-Bethe and independent atom model plus screening corrected additivity rule approaches. Additionally, we also report the appearance energies (AEs) and Wannier exponents for 36 of the 38 main cationic fragments observed in our experiments. Our experimental TICS data are typically found to be in good agreement with our theoretical results, and with other experimental and theoretical TICS data of 1-butanol currently available in the literature. Agreement of our AEs and the previous data, again where a comparison is possible, is also found to be satisfactory.
