Structural isomerization to open-chain alkenes was observed in the photolysis of methylcyclohexane 1,2-dimethylcyclohexane, 1,3-dimethylcyclohexane and 1,4-dimethylcyclohexane; cis-trans geometrical isomerization was also found in the dimethylcyclohexanes. The results of deuterium labelling experiments on methylcyclohexane and examinations of the product distributions suggest that biradicals are intermediates of both types of isomerization. The lifetime of the biradical state is assumed to be a few times the rotation time around a CC.
