    The reactive states of ions: Dimethyl-hexadienes and tetramethylcyclobutenes (1975)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 10 (1975), S. 1067-1074

    Notizen: The principal decomposition routes of molecular ions of cis, cis-3,4-dimethyl-2-4-hexadiene, cis, trans-3,4-dimethyl-2,4-hexadiene, cis-1,2,3,4-tetramethylcyclobutene and trans-1,2,3,4-tetramethylcyclobutene were studied using ion kinetic energy spectroscopy. Evidence indecates that loss of radicals from [M]+· appears to proceed via an electronically excited state, while loss of a neutral molecule appears to involve complete equilibration of structure within the system, or may involve both ground state and excited state pathways.

    The structure of the ion: An ion kinetic energy spectrometry study (1977)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 12 (1977), S. 150-152 
    Details
    ISSN: 0030-493X
    Schlagwort(e): Chemistry ; Analytical Chemistry and Spectroscopy
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: The kinetic energy release (T) values for the loss of CO from ions from five compounds have been obtained and are consistent with at least two different structures for the ion. This result is supported by the T value obtained for the decomposition of the molecular ions.

    The mass spectrometry of polychlorinated dibenzo-p-dioxins (1979)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 14 (1979), S. 9-16 
    Details
    ISSN: 0030-493X
    Schlagwort(e): Chemistry ; Analytical Chemistry and Spectroscopy
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: The negative ion chemical ionization mass spectra of polychlorinated dibenzo-p-dioxins using oxygen, methane and methane/oxygen are reported together with their methane positive ion chemical ionization mass spectra and conventional electron impact spectra. The methane/oxygen negative ion chemical ionization mass spectra proved to be the most useful of the negative ion spectra for structure determination.

    The effect of ion preparation on kinetic energy release: Substituent and leaving group effects on the reactivity of the [C6H5CO]+ ion (1976)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 11 (1976), S. 1101-1104 
    Details

    Thema: Chemie und Pharmazie
    Notizen: Ion kinetic energy spectrometry has been utilized to investigate the loss of CO from [p-Z-C6H4-CO]+ and [C6H5CO]+ ions generated from substituted acetophenones and benzo-phenones. The variation of the leaving group in forming the [C6H5CO]+ ion has no detectable effect on the kinetic energy release observed in the subsequent decomposition reaction. A substituent effect consistent with the assumption that substituted benzoyl ions have no memory of their origin is also observed.
