Abstract The ionization potentials of sulfurtetrafluoride have been measured using threshold photoelectron spectroscopy and com pared with theoretical calculations. The decay of SF4+ has been studied by photoionization mass spectrometry and photoion-photoelectron coincidence. The break-down graphs reveal competing decay processes. Bond dissociation energies in SF4+ have been calculated.

Dissociative photoionization mass spectrometry has been used to measure the PhCO+ appearance energies for several benzoyl compounds. Based on these threshold measurements, an experimental 298 K heat of formation of 738.8 ± 3.3 kJ mol−1 is obtained for the benzoyl cation. The experimental results are supported by high-level ab initio calculations.
