Collision energy effect on the H′ + BrH (ν = 0, j = 0) → H′Br + H reaction: A quasi-classical trajectory study

► The cross sections for collision energies from 0.5 to 2.0 eV are determined. ► The rotational, vibrational and translational fractions are presented. ► The repulsive character of the potential energy surface is explored. ► The alignment and the orientation of H′Br are found to be close relation to Ec.
