Abstract
PREVIOUS work carried out at the Mass Spectrometry Centre of the University of Liège has shown the specific behaviour under electron impact of cis and trans isomers in a series of pairs of cyclanic stereoisomers. It has been especially pointed out in 1,2-dialkyl derivatives of cyclopropane1, cyclobutane2, cyclopentane3 and cyclohexane4 that in the ionized state the cis isomer is less stable than the corresponding trans isomer (that is, the relative abundance, expressed as a fraction of total ionic current for 70 V. energy electrons, of molecular ions of a cis isomer is smaller than that for the corresponding trans molecule).
