Integral cross-section and stereodynamics study of the reaction O(1D)+H2($v = 0$, $j = 0$) → OH + H is undertaken using the quasiclassical trajectory (QCT) method for the collision energy is in the large length of 1.3 to 43 kcal/mol using Dobbyn and Knowles (DK) surface, and the obtained results are compared with those available from earlier available calculated results on the BR surface. The integral cross sections obtained from the quasiclassical trajectory method are in good agreement with those of Chebyshev wave packet method for collision energies above 0.2 eV.We also investigated the vector correlations and polarized dependent differential cross sections (PDDCS) at different collision energies. It is demonstrated that the alignment and state distribution significantly decrease with increase in the collision energy.
