Effect of Collision Energy on the Reactivity O⁺+T₂→OT⁺+T by the Quasiclassical Trajectory Method

The reactivity O⁺+T₂→OT⁺+T is studied by the quasiclassical trajectory method on the RODRIGO potential energy surface at the collision energies of 1.0, 1.3, 1.6 and 1.9 eV, respectively. The four polarization−dependent generalized differential cross sections (PDDCSs) (2π/σ)(dσ₀₀ /dω_t ), (2π/σ)(dσ₂₀ /dω_t ), (2π/σ)(dσ₂₂₊/dω_t ) and (2π/σ)(dσ₂₁₋ /dω_t ) are calculated in the center-of-mass frame. Furthermore, the P(θ_r ) distribution describing the k–j^′ correlation, the distribution of dihedral angle P(φ_r ) and the distribution of P(θ_r ,φ_r ), which describes the angular distribution of product rotational vectors in the form of polar plots in θ_r and φ_r are also investigated. The results demonstrate that the stereo-dynamical properties of the title reactivity are sensitive to collision energies.
