The RRKM theory has been used to interpret experimental measurements of the decomposition of excited c-C4H7T and c-C4D7T following T-for-H and T-for-D substitution in recoil tritium experiments. An expression is obtained for calculating the pressure dependence of decomposition to stabilization. It is found that (1) rotational effects are unimportant for either c-C4H7T or c-C4D7T decomposition; (2) when the excitation function for T-for-H substitution in c-C4H8 is approximated by one derived from molecular beam experiments, the displaced H atoms carry on the average 40% or more of the incident T translational energy; (3) for similar T-for-H and T-for-D excitation functions, displaced H and D atoms have nearly the same average kinetic energies.
