Quantum and Quasiclassical Dynamics of the ${\rm\bf C}(\bf ^3P)$ + ${\rm\bf H_2}(\bf ^1\Sigma_g^+)$ $\rightarrow$ ${\rm\bf H}(\bf ^2S)$ + ${\rm\bf CH}(\bf ^2\Pi)$ reaction: Coriolis Coupling Effects and Stereodynamics

The dynamics of ${\rm\bf C}$ + ${\rm\bf H_2}$ $\rightarrow$ ${\rm\bf H}$ + ${\rm\bf CH}$ reaction is theoretically studied using the quasiclassical trajectory and quantum mechanical wave packet methods. The analysis of reaction probabilities, integral cross sections and rate coefficients reveal the essential coriolis coupling effects in the quantum mechanical wave packet calculations. The calculated polarization-dependent differential cross section, P($\theta_r$) and P($\phi_r$) show that the $\bf j'$ of product rotational angular momentum is not only aligned along the y-axis and the direction of the vector $\bf x+z$, but also strongly oriented along the positive y-axis.

Time-dependent quantum mechanical wave packet dynamics

Starting from a model study of the collinear (H, H2) exchange reaction in 1959, the time-dependent quantum mechanical wave packet (TDQMWP) method has come a long way in dealing with systems as large as Cl + CH4.
