Dynamics of OH + O2 vibrational relaxation processes†
Abstract
The vibrational relaxation processes occurring during collisions of O2 and OH are investigated for vibrationally excited O2 (OH) colliding with OH (O2) in its ground state. All calculations employed the quasiclassical trajectory method and the realistic double many-body expansion (DMBE I) potential energy surface for ground-state HO3. Although a multiquantum mechanism turns out to dominate, two regimes for deactivation of high and low excited molecules have been found. A comparison with available experimental data is also reported.
