Quasi-classical trajectory method is used to investigate the influence of rotational excitation on the vector properties of the dynamics for the reaction O+HBrOH+Br based on the abinitio potential energy surface. At the collision energy 0.3 eV, we discuss the polarization-dependent differential cross sections (PDDCSs), the distribution P(r) describing k - j correlation, and the distribution P(r) describing k - k- j correlation. The calculated results suggest that the product rotational polarization becomes weaker as the rotational quantum number increases and the products are mainly forward scattered.
