Local modes and complex formation in H+OH collisions: Collinear reactions
Journal Article

· J. Chem. Phys.; (United States)
We compute quasiclassical trajectories on the Schinke--Lester potential energy surface to study complex formation in collinear H+OH collisions at relative translational energies between 0.5 and 1.0 eV. At all energies except those just above the entrance channel barrier, the great majority of collisions are direct. Vibrational phase relationships and energy resonances determine the probability of forming a complex and its lifetime. At 0.5 eV we found two trajectories that followed regular, periodic paths for 10--12 vibrations. At higher energies long-lived complexes are characterized by chaotic motion, a pattern of beats between local modes, and a tendency to share energy.
