Double ionization energies of the fluoroethane molecules C2H5F, CH3CHF2, CH2FCHF2, CH3CF3, CHF2CF3 and C2F6 measured by double-charge-transfer spectroscopy

Abstract

The results are reported of an experimental determination by double-charge-transfer spectroscopy of the previously unknown double ionization energies of the fluoroethane molecules C₂H₅F, CH₃CHF₂, CH₂FCHF₂, CH₃CF₃, CHF₂CF₃ and C₂F₆. Since double-charge-transfer spectroscopy also gives information about the single ionization energies of molecules, the single ionization energies of CH₂FCHF₂ and CHF₂CF₃ have been measured for the first time.
