Propargyl Stabilisation Energy For the alkynyl‐substituted olefines 1–14 activation parameters for the geometrical isomerisation have been determined in the gasphase by the single‐pulse shoke‐tube technique. By comparison of these barriers with the corresponding one of the isolated double bonds, each corrected by the steric energy contribution of the ground and transition state, a value of 7.8 ± 1.3 kcal · mol −1 for the propargyl stabilisation energy (PrSE) has been derived.
