“…Band I, whose maximum is observed at 21.7 eV, can be attributed to the satellite structure originating from the 4a orbital (with a HF energy of 24. exhibits maxima at 40.5 and 43.8 eV. As the 1a orbital corresponds essentially to the F 2s orbital, a photoelectron peak with a binding energy around 40 eV occurs in many fluorine containing molecules, for example, CF 4 [54], SF 6 [55] and SiF 4 [56]. However, the peak profile and the number of separate components contributing to the structure, varies from molecule to molecule.…”

“…In the photoelectron spectrum recorded at 80 eV (Figure 3), band G is the dominant peak, as would be expected based on a consideration of the energy dependence of the F 2p photoionization cross section. Moreover, the β-parameter for band G at 42 eV (0.8) is typical of that for molecular orbitals having a strong F 2p lone-pair character [54].…”

“…In this experiment, the ionic fragments of CF 3 + , CF 2 + , CF + , F + and C + from CF 4 are clearly resolved. We compare our results with electron impact ionization [33,36,47,48,53], and photoionization studies [8,[11][12][13]15,21,22,59]. …”

“…The two lowest unoccupied orbitals (LUMOs) in the ground state of this molecule are 5a 1 and 5t 2 [8]. The five outer-valence orbitals are 1t 1 , 4t 2 , 1e, 3t 2 , and 4a 1 and their vertical ionization energies are known from highresolution HeI and HeII Photoelectron Spectra (PES) to be 16.20 eV, 17.40 eV, 18.50 eV, 22.12 eV and 25.12 eV respectively [62].…”
