The energies calculated for tetranitrogen tetrasulfide, S4N4, by the CNDO/BW theory favor a structure with coplanar nitrogen atoms and not a structure with coplanar sulfur atoms. Both structures have been proposed from experimental studies. Localized molecular orbitals are calculated for S4N4 and used to choose the appropriate Lewis structure for the molecule. The hybridization at the nitrogen and sulfur atoms is discussed. There is electron delocalization in the molecule, the S—N bond is a bent bond involving pure p-orbitals on the sulfur and nitrogen atoms and there is a pure p-bent bond between the sulfur atoms on the same side of the coplanar nitrogen atoms. There is no N—N bond in S4N4.

Abstract The electronic structure of dodecahedral octacyanides of molybdenum IV and V is described in terms of SCCC molecular orbitals. Five MO's resemble d orbitals of the central atom. The splitting of appropriate levels is almost exactly the same as that following from the crystal field theory for G4/G2 ~ 0.7. According to the theory stable Mo(CN)84- is dodecahedral and stable MO(CN)83- is antiprismatic. In the dodecahedron the A-type ligands are bonded more strongly than the B-type ligands.

The complex {1,1’-[ o-phenylenebis (nitrilomethylidyne) ] di-2-naphtholato} copper(II) was optimized by the DFT method at B3LYP/LANL2DZ level, and the frontier molecular orbitals, natural bond orbitals, nonlinear optical properties and Mülliken charge population of the optimized complex were exploited and analyzed. The calculated results show that the complex has stable structure and it keeps some potential applications in optic materials field.


Helium 584 Å radiation produces photoeleetron spectra from water and deuterium oxide, which show extensive vibrational fine structure. The results are discussed in terms of the electronic structure of the molecule, and the bonding characteristics of the various molecular orbitals. Water is inferred to have only three configurationally distinct ionization potentials smaller than 21.22 eV.
