    Application of 19F NMR spectroscopy to the study of equilibrium dynamics of uranyl(2+)-fluoride complexes (1995)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 33 (1995), S. 20-26 
    Details
    ISSN: 0749-1581
    Keywords: NMR ; 19F NMR ; Magnetization transfer ; 2D-EXSY ; Uranyl(2+)-fluoride complexes ; Ligand exchange ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: One- and two-dimensional magnetization-transfer 19F NMR methods were applied in a quantitative study of the fluoride exchange for uranyl(2+)-fluoride complexes in aqueous solution. The applicability of these techniques and the classical lineshape analysis is discussed, and the quality of the results (rate constants and relaxation rates) obtained by the three methods is compared.

    Conformational studies on B/C-cis- and B/C-trans-morphinan derivatives (1995)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 33 (1995), S. 913-916 
    Details
    ISSN: 0749-1581
    Keywords: NMR ; NOE ; selective 2D J spectroscopy ; B/C-cis- and B/C-trans-morphinans ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: An unambiguous structural differentiation of B/C-cis- and B/C-trans-morphinan derivatives (thebainone-A and β-thebainone-A and their 7,8-dihydro derivatives) is provided. The structures were confirmed by NOE difference spectroscopy and selective 2D J-INEPT experiments. In addition, full a priori 1H and 13C NMR assignments of the isomeric pairs studied are presented.
