    Darstellung und Eigenschaften von Vanadyl(IV)-Saccharinat (1993)
    Springer
    Monatshefte für Chemie 124 (1993), S. 355-366

    Notes: Summary The synthesis of a new vanadyl(IV)/saccharin complex is reported. Its bonding characteristics differ considerably from all known divalent metal-saccharinates. In this complex a VO(OH)+ moiety is coordinated to a saccharin molecule through its carbonyl oxygen and to a saccharinate ion through its deprotonated nitrogen. Two water molecules complete the coordination sphere. X-ray powder diagrams, infrared- and electronic absorption-spectra were recorded and analyzed for the characterization of the compound and its coordination properties. Besides, the magnetic susceptibility and the thermal behaviour were also investigated.

    Thermal Behaviour of Pharmacologically Active Lithium Compounds (2000)
    Springer
    Journal of thermal analysis and calorimetry 61 (2000), S. 29-35

    Topics: Chemistry and Pharmacology
    Notes: Abstract The thermal decompositions of a series of simple lithium compounds (carbonate, sulfate, acetate, citrates, aspartates and glutamates) currently used in the treatment of manic-depressive psychosis and related disorders were investigated by means of TG and DTA measurements in oxygen atmosphere. Pyrolysis residues were characterized by infrared spectroscopy. The stabilities of the hydrates and intermediate phases generated during the degradation processes are discussed.

    Infrared, Raman and pre-resonance Raman spectra of vanadyl(IV) tetraphenylporphyrin (1992)
    Chichester [u.a.] : Wiley-Blackwell
    Journal of Raman Spectroscopy 23 (1992), S. 489-494

    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.
