Studies on the Stereodynamics of the O (3P) +H2 reaction have been performed via the Quasiclassical trajectory method (QCT) at collision energy of 34.6 kcal/mol on BMS1 potential energy surface [Brand(a)o et al, J.Chem.Phys.121,8861 (2004)].The distribution of angle between k and jP (θr) and the dihedral angle distribution P (φr) characterizing the k-k-j correlation are calculated and discussed.We also present two polarization dependent generalized differential cross-sections (PDDCSs) (2π/σ)(dσ00/dωt) and (2π/σ)(dσ20/dωt) in the center of mass flame.
