    Notes: The Raman spectra of polycrystalline samples of the metavanadates MIIV2O6 (with M = Ca, Cd, Cu and Mg), belonging to the brannerite structural type, have been recorded. A general assignment, supported by comparisons with known vibrational properties of other oxovanadium species, is proposed. The compounds only give poorly defined IR spectra, which are not useful for the analysis of the vibrational behaviour.

    Notes: A study of the electronic, infrared, Raman and pre-resonace Raman spectra of the solid complex tris(8-hydroxyquinolinato)vanadium(III) was performed. The excitation profiles of the vibrational modes that show preresonance on excitation with laser lines within the electronic bands in the visible region are reported and, on this basis and molecular orbital calculations, several vibrational and electronic absorption bands were assigned.

    Notes: The resonance Raman effect in solid Na5[Cu(HIO6)2].16H2O at room temperature was investigated and the experimental excitation profiles were obtained. From the analysis of the overtone progression of the ν1(A1g) mode, corresponding to the I—O symmetric stretching vibration, the X11 anharmonicity constant was determined. The dependence of the Raman intensities on the scattered frequency is briefly discussed.

    Raman, pre-resonance Raman and electronic spectra of iron(II) saccharinate (1992)

    Notes: The Raman spectrum of solid [Fe(Sac)2 (H2O4)] · 2H2O was recorded and assigned. Some comparisons with the spectra of the related copper(II) and nickel(II) complexes were also made. The excitation profiles of the vibrational modes that show pre-resonance on excitation with laser lines within the electronic bands are reported. On this basis, and with the aid of a semi-empirical extended Hückel MO calculation, the assignment of the metal - ligand vibrations and the interpretation of the electronic spectrum could be reinforced.

    Notes: The resonance Raman spectrum of a polycrystalline sample of AgMnO4 allowed a wider insight into the vibrational properties of the MnO4- ion in this lattice. This study confirmed important covalent contributions to the overall structure and strong cooperative effects between the ions present in the unit cell.

    Notes: The Raman spectrum of Na[VO2Q2] was recorded and assigned by comparison with related species. The excitation profiles of the vibrational modes that show pre-resonance on excitation using laser radiation within the electronic bands are reported and three different types of profiles could be found. The electronic spectrum of the anion was also recorded and interpreted with the aid of a semi-empirical MO calculation. This calculation, together with the results of the pre-resonance experiments, also reinforced some of the vibrational assignments.

    Infrared, Raman and pre-resonance Raman spectra of vanadyl(IV) tetraphenylporphyrin (1992)

    Notes: The infrared and Raman spectra of vanadyl(IV) tetraphenylporphyrin were recorded between 1600 and 200 cm-1. Assignment of most of the vibrational modes was done by comparison with other related compounds. The V—N and V=O metal - ligand vibrations could be clearly identified. Pre-resonance experiments were performed, using different radiation from an argon ion laser, in the energy range between the main electronic transitions of the complex [the Soret band and the (α + β) doublet]. Analysis of the excitation profiles suggests that all the enhanced bands contribute to both the A and B terms of Albrecht's equation.

    Notes: Information on the vibrational and electronic properties of the [VO(biuret)(SO4)] · 3H2O complex was improved in order to gain a deeper insight into the characteristics of the metal-ligand bonds. Normal Raman and pre-resonance Raman studies were performed, which allowed a better characterization of the metal-ligand modes and a thorough analysis of the electronic spectrum. The results were also compared with theoretical semi-empirical molecular orbital calculations.
