Item Appearance and Ionization Potentials of Ions produced by Electron-impact on some Phosphorus-Fluorine Compounds: the Phosphorus-Phosphorus Bond Dissociation Energy in Diphosphorus Tetralluoride(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (11), 1974) Dean, Christopher R. S.; Finch, Arthur; Gardner, Peter J.; Payling, David W.The ionization potentials of P2F4, PF3 PF2H and PF2I and the appearance potentials of the PF+2 ion from these species are reported. The ionization potential of the PF2˙ radical is estimated using approximations for the PF2—X (X = F, I and H) bond dissociation energies. The P—P bond dissociation energy in diphosphorus tetrafluoride is estimated as 57 ± 10 kcal mol–1.Item Molecular complexes of substituted thiophens with σ and π acceptors: Charge transfer spectra and ionization potentials of the donors(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (3), 1973) Aloisi, Gian Gaetano; Pignataro, SalvatoreCharge transfer complexes of substituted thiophens as donors with tetracyanothylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone, chloranil and iodine have been studied spectrophotometrically. From the energies of the charge transfer transitions, the ionization potentials of the donors have been obtained. Comparison with those measured by electron-impact mass spectrometry, shows that the thiophens behave as π donors with all four acceptors. In the case of iodine the stability constants of the complexes support a π→σ* interaction. Some evidence is given for the role of inner valence orbitals in the complexes.
