By adopting an sp(2) hybridised model, it is found that the overlap integral for two adjacent lone pairs is numerically greater for the trans isomer. On the basis of 1-electron Huckel theory, this suggests that cis isomers are more stable than trans, contrary to the predictions of conformational analysis. Commonly, non-bonded interactions lead to the stabilisation of trans isomers, but when these repulsions are not dominant, the cis isomers are always the more stable.
