Notes:
The techniques of Fourier transform spectroscopy and high pressure mass spectrometry have been used to investigate the ionization energy (IP) of SF5 via electron exchange reactions. An IP of 9.60±0.05 eV has been derived from this data, which is in disagreement with estimates from flowing afterglow measurements (IP≥10.15 eV). In addition, no evidence has been found for a fluoride transfer equilibrium involving CF+3 and SF6, which was thought to interrelate the heats of formation of CF+3 and SF+5. Our results are consistent with the recommended (SF5–F) bond strength of ∼4.0 eV, and suggest an energy threshold for SF+5 production from SF6 of 13.6 eV.
