    Description / Table of Contents: Photoelectron Spectra and Molecular Properties. 133. Trifluoromethyldisulfane and Derivates F3CSSX (X=CF3, F, Cl, Br)The He(I) photoelectron spectra of trifluoromethyldisulfane F3CSSH and its derivatives F3CSSX (X=CF3, F, Cl, Br) are assigned by Koopmans correlations, IEnv = -εjMNDO, with MNDO eigenvalues and by radical cation state comparison. Of special interest are the nSπ/nSπ splittings, which amount to 1.15 eV F3C—SS—F or 0.87 eV in F3—SS—Cl, and the dependance of which on the dihedral angle ω(XS—SX), on the SS bond length and on the acceptor effect of the F3C substituents is discussed.
    Notes: Die He(I)-Photoelektronen-Spektren von Trifluormethyldisulfan F3CSSH und seinen Derivaten F3CSSX (X = CF3, F, Cl, Br) werden durch Koopmans-Korrelationen, IEnv = -εjMNDO, mit MNDO-Eigenwerten und durch Radikalkationzustands-Vergleiche zugeordnet. Von besonderem Interesse sind die nSπ/nSπ- Aufspaltungen, die in F3C—SS—F 1,15 eV oder in F3C—SS—Cl 0,87 eV betragen und die in Abhängigkeit vom Diederwinkel ω(XS—SX), der SS-Bindungslänge und dem Akzeptor-Effekt der F3C-Substituenten diskutiert werden.
