Photon Echoes in Multilevel Systems surfaces, subject to a constraint defined by the Franck-Condon principle. A photon echo results when and if the excited electronic state wavefunction and ground electronic state wavefunction overlap.

Electronic Spectroscopy of Metal-Metal σ-Symmetry Interactionsal (dσ→dσ*) or axial-ligand charge transfer (L(σ)→dσ*); the relative energetics are determined mainly by metal-metal bond strength and axial-ligand reducing character. In some cases, both σ→σ* transitions are observed. Relatively weak electronic absorption bands are attributable to dπ→dσ*(M.) and dπ

Metal Metal Bonds in Edge Sharing Bioctahedraedron. Examples of d.-d., d.-d., d.-d., d.-d., d.-d. and d.-d. systems are cited. The simplest approach to the bonding is to consider only the overlaps of pairs of d orbitais to give σ, π, δ, δ*, π* and σ* orbitais, increasing in energy in that order. This picture is unsatisfactory because there are

AB Initio Calculation of Electronic Transitions in Transition Metal Complexesise restricted Hartree-Fock, configuration interaction, and multiconfigurational self-consistent-field calculations. Their results are compared with experimental spectra. The systems considered are NiF.., CoO.., CuF.., CoCl.., VO(H.O).. and MnO... A great deal of attention is paid to the influence o

The Orthonormal Operator Formulation of Symmetry-Based Ligand Fields: Rhombohedral Hierarchies as a this operator space are discussed: atomic bases, consisting of irreducible tensor operators of the three-dimensional rotation group R3; molecular bases, consisting of basic symmetry operators, basic energy operators, irreducible tensor operators of the octahedral rotation group 0, or finally, the r

Tetracyanobiimidazole: A Polyploid of Distinctionetracyano-2,2′-biimidazole and especially its reactions as a ligand for low valent metals. Because of the acidity of the N-H protons, (pK. = 2.1, pK. = 5.5,) complexes of this ligand are always of the dianion. The survey includes compounds of Rh(I), Ir(I), Cu(I), Pt(II), and Mo(0).
