โฆ Synopsis
We discuss the dissociatian of a molecule HXD, when the dissociation occurs OT: ;t repulsive surfLm with a single saddle point. We cnlvulate the order of magnitude of the intramolecular isotope effect, and find it in apeemeat uith espcrimcnbl observations.

The thermal unimolecular decomposition of diethyl carbonate-1,1,1,2,2-d5 has been examined in the high-pressure-limiting region. The observed chemistry is consistent with a simple, competitive two-channel model: The intramolecular isotope effect k H / k D has been determined, and the relative Arrhe
The thermal decomposition of deuterated ethyl chloride CHzDCHzCl was studied in a static system in the pressure range of 0.1-26 torr, and the Arrhenius expression for the overall decomposition at the high-pressure limit and in the temperature range of 670-1100 K was found to be k , = 1013.33\*0.10 e
