The limiting low pressure yield behavior has been characterized for gas phase substitution reactions of energetic 3H and 18F atoms with aliphatic and alicyclic substances. The limiting yields correlate well with the respective critical energies for secondary unimolecular decomposition. The interpretation of this behavior leads to quantitative descriptions for the hydrogen-for-hydrogen and F-for-F primary product internal excitation energy distributions together with approximate descriptions of total energy disposal for the threshold hydrogen-for-hydrogen processes.
