    Mass spectral studies on prostaglandins. Prostaglandin A1 (1975)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 2 (1975), S. 190-196 
    Details
    ISSN: 1052-9306
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The mass spectroscopic behaviour of prostaglandin A1 and its methyl ester has been studied. Mechanisms are suggested for the majority of fragmentation processes occurring in the spectra of these compounds. The proposed mechanisms have been confirmed by low electron voltage spectra, measurements on metastable ion decompositions, high resolution mass measurements and deuterium labelling.

    Mass spectral studies on prostaglandins. II - prostaglandins E1 and E2 (1976)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 3 (1976), S. 4-13 
    Details
    ISSN: 1052-9306
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The mass spectroscopic behaviour of the methyl ester of prostaglandins E1 and E2 has been studied with the aid of low eV spectra, measurements on metastable ion decompositions and high resolution mass measurements. Mechanisms are proposed for the formation of the majority of the abundant fragment ions of these biologically important compounds. The mass spectra of free acids are also discussed.

    The mass spectral fragmentation of 9α-hydroxy steroids and related compounds (1977)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 4 (1977), S. 376-380 
    Details
    ISSN: 1052-9306
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The fragmentation processes occurring in various 9α-hydroxy steroids upon electron have been studied. The mechanisms proposed for the formation of the prominent ions in these spectra have been confirmed with the aid of deuterium labelling, measurements on metastable ion decompositions, low eV spectra and high resolution mass measurements. The fragmentation of the corresponding 9-oxo-9,10 seco steroids, which shows analogy to that of the 9α-hydroxy compounds in many respects, has also been discussed.

    The mass spectral fragmentation of 1,4-butanediol (1977)

    Notes: The behaviour of 1,4-butanediol under electron impact at 70 and 12.5 eV has been studied with the aid of high resolution mass spectra. Based on metastable ion decompositions and deuterium labelling, mechanisms are proposed for the formation of the abundant ions of this compound.

    Mass spectral studies on prostaglandins. V - Deuterated analogues of prostaglandin F2α (1978)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 5 (1978), S. 544-550

    ISSN: 0306-042X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: In order to check the fragmentation mechanisms proposed in the preceding paper of this series the mass spectral behaviour of some deuterated analogues of prostaglandin F2α have been studied. In general, the investigation of these compounds confirmed the previous assumptions and shed light on some further details of the fragmentation pathways.
