Cross sections for complex formation in H + OH collisions

Abstract

We have computed cross sections for complex formation in H + OH collisions as a function of initial translational energy and OH vibrational and rotational state. The translational energy curve rises from a threshold below 0.2 eV to a maximum near 0.3 eV, then declines exponentially. The initial OH vibrational and rotational state strongly influences complex formation in low (0.2 eV) kinetic energy collisions. Rotation particularly enhances complex formation. At higher kinetic energies (0.5 eV) rotation and vibration inhibit complex formation.
