    The NMR spectra and conformations of cyclic compounds - IV: The conformation of 3,4-cyclopropyl-proline (1970)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 2 (1970), S. 173-177

    ISSN: 0030-4921
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: The 1H magnetic resonance spectrum of the title compound has been completely analysed, using 60, 100 and 220 MHz spectrometers. The values of the chemical shifts and coupling constants obtained confirm the proposed structure and also provide information on the conformation. The molecule is slightly boat-shaped.

    1H and 13C NMR spectra of benzyl compounds (1972)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 4 (1972), S. 585-589 
    Details
    ISSN: 0030-4921

    Topics: Chemistry and Pharmacology
    Notes: Proton and carbon-13 spectra of benzyl compounds of the general formula (C6H5CH2)nX with a large variety of X substituents have been measured. While a linear relationship between the CH2 chemical shift and the substituent electronegativity was found both for 1H and 13C, large deviations from linearity were observed for transition metals such as titanium and zirconium. These later results are correlated with the X-ray studies of the latter compounds.

    13C n.m.r. spectra of lysergic acid derivatives: II - dihydrolysergamidesFor Part I, see Ref. 1. (1977)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 9 (1977), S. 218-223

    Topics: Chemistry and Pharmacology
    Notes: The conformations of dihydrolysergamides and 10-methoxydihydrolysergamides have been inferred from the study of the chemical shifts of the amide hydrogens and their temperature dependence. The 13C chemical shifts have been shown to be sensitive to conformational changes of the piperidine ring. The results indicate that the conformation of the latter depends both on the substituent in position 10 and on the solvent.

    Pentafluorobutane; an example of long-range five bond H—F coupling (1971)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 3 (1971), S. 599-604

    ISSN: 0030-4921
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The complete analysis of the spectrum of 2,2,4,4,4-pentafluoro-n-butane is reported. From the sum of the vicinal proton-fluorine coupling constants an estimate of the conformational energy has been obtained and successively the long-range coupling of the individual conformers has been calculated.

    Dioxidobutane: A comparison between high field and Eu-shifted PMR spectra (1973)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 5 (1973), S. 53-56 
    Details
    ISSN: 0030-4921
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Complete analysis of the high field spectrum of the title compound gives well determined parameters in all cases; the value of the CH—CH coupling is in agreement with free rotation around this bond. In contrast, the Eu-shifted spectrum does not allow such a complete analysis because of lack of resolution. Shift dependence on concentration and temperature is reported and discussed.
