In the past decade, we have developed the time-dependent wave packet (TDWP) method to compute full-dimensional differential cross sections (DCS) for four-atom reactions and reduced-dimensional DCSs for six-atom reactions involving methyl group, and applied to the prototypical H 2 + OH ↔ H + H 2 O The rest of this article is organized as follows: Section 2 outlines the numerical parameters employed in our calculations. Our quantum dynamical results for the title reaction are detailed in Section 3. Section 4 serves as a summary of our conclusions.
