چکیده

A modified ab initio potential energy surface ~PES! is used for calculations of ozone recombination and isotopic exchange rate constants. The calculated low-pressure isotopic effects on the ozone formation reaction are consistent with the experimental results and with the theoretical results obtained earlier @J. Chem. Phys. 116, 137 ~2002!#. They are thereby relatively insensitive to the properties of these PES. The topics discussed include the dependence of the calculated low-pressure recombination rate constant on the hindered-rotor PES, the role of the asymmetry of the potential for a general X1YZ reaction (YÞZ), and the partitioning to form each of the two recombination products: XYZ and XZY . © 2002 American Institute of Physics. @DOI: 10.1063/1.1488577#
