    Notes: Summary Mean amplitudes of vibration of the isostructural molecules HBCl2, HAlCl2 and HGaCl2 and of its deuterated analogous have been calculated from spectroscopic data in a wide temperature range. The results are briefly discussed and some comparisons with data of related species are also made.

    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.

    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.

    Raman, pre-resonance Raman and electronic spectra of the anion [VO2Q2]- (Q = 8-hydroxyquinolinate) (1992)

    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.

    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.
