    Notes: Small nickel clusters up to the tetramer are investigated within the framework of the local spin density functional theory. Several competitive states are studied for the dimer. Both the geometry and the spin state are optimized for several starting symmetries in the case of the trimer and the tetramer. Moreover, all those calculations are followed by a vibrational analysis in order to discriminate between real minima and saddle points on the potential energy surface. It is found that Jahn-Teller deformations play an important role in determining transition-metal cluster geometries. Equilibrium geometries, electronic configurations, binding energies, magnetic moments, and harmonic frequencies are reported in this work.   © 1998 John Wiley & Sons, Inc.

    Description / Table of Contents: Raman and Resonance Raman Spectra of the Permanganates of Tetraphenylarsonium and TetraphenylphosphoniumThe measurement of Raman and resonance Raman spectra of the title compounds allow a wider insight into the vibrational properties of the MnO4- ion in these lattices. The anharmonicity constants and harmonic vibrational frequencies for the totally symmetric stretching vibration as well as the X13 anharmonicity constant could be determined from the resonance Raman spectra. The results are briefly discussed.
    Notes: Die Messung von Raman- und Resonanz-Raman-Spektren der Titelverbindungen ermöglichte weitere Einsicht in das schwingungsspektroskopische Verhalten des MnO4--Ions in diesen Gittern. Aus den Resonanz-Raman-Messungen konnten weiterhin die Anharmonizitätskonstanten und harmonische Schwingungsfrequenzen für die totalsymmetrische Valenzschwingung sowie die X13-Anharmonizitätskonstante ermittelt werden. Die Ergebnisse werden kurz besprochen.

    Notes: The resonance Raman spectra of potassium μ-oxobis[pentacyanomanganate(III)] cyanide, K7[Mn2O(CN)10]CN, were measured using exciting lines at 356.4, 406.7, 530.9, 568.2, 603.5, 647.1 and 676.4 nm. By combining these data with those obtained previously (excitations at 457.9, 476.5, 488.0, 496.5, 514.5 and 608.6 nm), the excitation profiles were plotted for three totally symmetric vibrations at 1880 (CNax strech), 527 (MnCax stretch) and 259 cm-1 (MnOMn stretch). It was found that the equation derived by Mingardi et al. can adequately express these excitation profiles and that the previous assignment of the electronic transition at 509 nm needs revision.

    Notes: The infrared and resonance Raman spectra of the solid complex hydroxophthalocyaninatomanganese(III) were obtained. The excitation profiles of some vibrational modes show resonance within the electronic bands in the visible region, and on this basis several vibrational and electronic absorption bands are assigned.

    Notes: The SER spectra of the complexes [Fe(CN)5(4-picolylamine)]3- and [Fe2(CN)10(4-picolylamine)]6- adsorbed on a silver electrode were investigated. The analysis of the frequency shift of the CN stretching mode indicated that both molecules adsorb via one or more CN ligand groups. For potentials more positive than 0.0 V the CN stretching frequency for both complexes moves towards higher wavenumbers charcterizing the presence of Fe(III) over the surface. The SER spectra of 4-picolylamine adsorbed on a silver electrode in solutions of pH 2.8, 6.5 and 10.3 were also investigated. From the data obtained it was concluded that 4-picolylamine in solution at pH 6.5 and 10.3 adsorbs on the electrode through the nitrogen of the pyridine ring.

    Notes: The resonance Raman spectrum of the MnO4- ion enriched in 18O and dispersed in a RbBr matrix was obtained. The symmetric stretching fundamental band and its first three overtones were measured for the five possible isotopomers, allowing an estimation of the corresponding harmonic frequencies and anharmonicity constants. An explanation for the observed trend in these constants is proposed.
