The study of the mass spectrum of the 1.2 dialkyl derivatives of the cyclopentane enabled us to point out a noticeable exaltation of the differences in the abundance of ions obtained at the expense of cis and trans isomers of those derivatives, when the energy of the electrons progressively decreases.
These differences, very important in the case of electrons of about 15 ev., are an outlook for the possibility of analizing mixtures of isomers pairs of this type.
The shape of the curves, which express the variation of the ions abundance versus the electron energy, allows to confirm the schemes of decomposition based on the interpretation of the observed metastable transitions.

## Abstract The influence of the energy of ionising electrons on the behaviour of monohalogeno‐substituted benzenes, has been studied. In proportion as this energy is decreasing, the stability of the molecular ions is increasing, but the stability still decreases from fluorobenzene to iodobenzene,
Correlations between mass spectra and molecular structure are attempted in a series of cis and trans 1,2-diaIkylcyclohexanes previously investigated. Rather large differences appear between abundances of main fragment ions, especially (P-R1)+ (parent ion having lost the Rl group) and (P-Rl-H)+, some
