For the vinyl-substituted olefines 1-14 activation parameters for the geometrical isomerisation have been determined in the gas-phase.By comparison of these barriers with the corresponding ones of the isolated double bonds, each corrected by the contribution of the steric energy to the ground and transition state, a value of 13.5 +/- 1.1 kcal mol-1 for the allyl stabilisation energy (ASE), defined as replacement of alkyl by vinyl, has been derived.
