The translational energy releases accompanying fromation of H ˙ and [CHO] + from [CHOH] +˙ , H ˙ and [CDO] + from [CDOH] +˙ , D ˙ and [CHO] + from [CHOD] +˙ and D ˙ and [CDO] + from [CDOD] +˙ have been calculated from the widths at half‐height of the respective metastable peaks. The energy releases for [CHOD] +˙ and [CDOD] +˙ are similar to each other in magnitude, but are both significantly larger than those for [CHOH] +˙ and [CDOH] +˙ . These differences are discussed in terms of the dynamical theory of energy partition. The larger energy releases for decompositions giving D ˙ are attributed to larger proportions of the kinetic energy being associated with the departing D ˙ in the transition states, as compared to H ˙ in the transition states for the decompositions yielding H ˙ .
