    Molecular complexes of substituted aryl diphenylmethyl sulphides with π-acceptors: Charge transfer spectra and ionization potentials of the donors
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (1), 1977) Reichenbach, Gustavo; Santini, Sergio; Aloisi, G. Gaetano
    Charge transfer complexes of substituted aryl diphenylmethyl sulphides, X1C6H4(X2C6H4) CH—S—C6H4Y, with tetracyanoethylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone and chloranil have been studied spectrophotometrically. The energy of the charge transfer transition is influenced by the substituents in Y, but is not affected by the substituents in X. The ionization potentials calculated from the energy of charge transfer transitions are in good accord with those measured by photoelectron spectroscopy. The nature of the donor orbitals is also discussed.

    Molecular complexes of substituted diphenyl sulphides with π acceptors. Charge transfer spectra and ionization potentials of the donors
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (10), 1974) Aloisi, G. Gaetano; Santini, Sergio; Sorriso, Salvatore
    Charge transfer complexes of substituted diphenyl sulphides as donors with tetracyanoethylene, 2,3-dichloro-5,6-dicyano-p-benzoquinone and chloranil have been studied spectrophotometrically. From the energies of the charge transfer transitions, the ionization potentials of the donors have been obtained. From the formation constants of the complexes and ionization potentials of the donors evidence has been obtained on the mixed nature of the donor orbital. The role of inner valence orbitals in the complex formation is also discussed.
