Quasi-classical trajectory study of the isotope effect on the stereodynamics in the reaction H(²S)+CH(X²Π; v=0, j=1)→C(¹D)+H₂(X¹Σ_g⁺)

The isotope effect on the stereodynamic properties in the title reaction is investigated by a quasi-classical trajectory (QCT) method on the 1¹A' potential energy surface at a collision energy of 23.06 kcal/mol. The angular distributions P(θ_r), P(ø_r), P(θ_r, ø_r), and the polarization-dependent generalized differential cross sections are calculated, which demonstrate the observable influences on the rotational polarization of the product by the isotopic substitution of H with D.
