title: Theoretical study of isotope effects on the stereodynamics of H⁺+HD and its isotopic variant D⁺+HD.
abstract: The stereodynamics for H(+)+HD and its isotopic variant D(+)+HD were studied with a quasi-classical trajectory (QCT) method at a collision energy of 0.7 eV on the ground 1(1)A' potential energy surface (PES). The polarization-dependent differential cross-sections (PDDCSs) in the center-of-mass frame are presented here. Furthermore, the distribution of the angle between k and j', p(θ                         (                            r                         )) and the distribution of the dihedral angle p(ϕ                         (                            r                         )) were calculated and are discussed. The results indicate that isotopic substitution exerts substantial effects on the differential cross-section and the product's rotational polarization.
