The field ionisation investigation of some stereoisomeric alkenes and alkyl halides reveals differences in the fragmentation behaviour with respect to direct bond rupture. As observation by itself of the thermodynamic stability of stereoisomeric molecules, or rather of their structure, does not suffice entirely to explain the observed differences, we offer here an interpretation of experimental results based on the interaction of the stereoisomeric compounds with the strong electric field. Finally, some fundamental conclusions are drawn about the applicability of the field ionisation method to the differentiation between stereoisomers.
