Effects of the Reagent Rotational Excitation on the Stereodynamics of the Reaction C(³P)+CH(X²Π)→C₂+H

Based on the 1²A" global three-dimensional adiabatic potential energy surface [Boggio-Pasqua et al., Phys Chem. Chem. Phys 2:1693-2000], a theoretical study of the stereodynamics of the reaction C(³P)+CH(X²Π) (v=0; j=0-$6)$ has been performed using the quasi-classical trajectories(QCT) method. The cross sections are caculated. The differential cross sections (DCSs) and the distributions of P(θᵣ), P(φᵣ) are pensented in detail at the selected collision energy of 0.3 eV. The product rotational alignment parameter $$ are also obtained as a function of the regent rotational quantum number. The results show that the reagent rotational excitation plays an important role in the title reaction.
