Ozone formation in ternary collisions: Theory and experiment reconciled

ORAL

Abstract

In this work, we present a theoretical study on the primary mechanism of ozone formation in the stratosphere, i.e., O+O2+M with M=Ar. Our approach is based on a direct treatment of the three-body process through a classical trajectory method in hyperspherical coordinates, without using the two-step approximation via intermediate complexes. As a result, after computing thermally-averaged coefficients for temperatures 5-900 K, we find that most O3 molecules appear in weakly bound states, which are further quenched, leading to a good agreement with available experimental data for temperatures 100-900K.
