Electron impact ionization of 1-butanol: I. Mass spectra and partial ionization cross sections
Name:
Publisher version
Abstract
Experimental measurements of the cations created through electron impact ionization have been undertaken for the primary isomer of butanol, using a Hiden Quadrupole Mass Spectrometer (EPIC 300) with a mass resolution of 1 amu. The mass spectrum recorded at an incident electron energy of 70 eV, normalized and placed on an absolute scale, reveals the relative probability of forming 76 different cations of butanol by either direct ionization or dissociative ionization. Individual partial ionization cross sections (PICS) for the 38 main cationic fragments, measured at electron energies in the range 10–100 eV, are also reported for the first time in this work.Citation

Electron impact ionization of 1-butanol: II. Total ionization cross sections and appearance energiesExperimental 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.

Electron impact ionization of 1-propanolExperimental measurements of the cations created in electron impact ionization have been undertaken for the primary isomer of propanol using a Hidden Quadrupole Mass Spectrometer (EPIC 300), with a mass resolution of 1 amu. The mass spectra recorded at an incident electron energy of 70 eV reveals the relative probability of forming 50 different cations, by either direct ionization or dissociative ionization. Individual partial ionization cross sections (PICS) for 31 different cations were measured for the first time in this work, for the incident electron energy range from 10 to 100eV. Also, appearance energies (AEs) and Wannier exponents for the 16 most intense cations formed in electron collisions with 1-propanol are reported. Where possible, those results are compared to those from an earlier investigation. Total Ionization Cross Sections (TICS) were also obtained from the sum of the measured PICS, for nearly all cations measured, and are compared to relevant data reported in the literature. In addition, as a part of this study, theoretical TICS were calculated using the Binary-encounter Bethe (BEB) and independent atom model with screening corrected additivity rule (IAM - SCAR) methods. Good agreement between current measured and calculated TICSs and corresponding earlier results was typically found.

Natural and unnatural-parity contributions in electron-impact ionization of laser-aligned atomsDifferential cross section measurements from laser-aligned Mg atoms are compared to theoretical calculations using both time dependent and time-independent formalisms. It is found that both natural and unnatural parity contributions to the calculated cross sections are required to emulate the data when the state is aligned out of the scattering plane.
