RATE CONSTANTS FOR OZONE FORMATION

The dynamics of collisions between an Ar atom and quasi-bound ozone, formed by colliding O2 with O to form O3*, has been studied using the quasiclassical trajectory method. The cross-sections and rate constants for stabilizing the highly exited quasi-bound ozone complex by the process O3* + Ar --> O3 + Ar, have been determined. As potential energy surface for the Ar-O3 system we use the ground state potential energy surface for ozone obtained by Sheppard and Walker (SW) coupled with an atom-atom potential for the intermolecular V(Ar)-O3 interaction. Due to the lack of a specifically calculated Ar-O3 potential, we used the Ar-O interaction from Ar-glyoxal.
