\begin{abstract}
The effects of HCl rotational excited states on the stereodynamics of
the Ca+HCl reaction are explored based on quasi-classical trajectory
(QCT) theory with potential energy surface (PES) {[}Verbockhave et al.,
J. Chem. Phys. 2005,122,204307{]}. Vibrational level v=0 and rotational
level j=0-3 are considered. The polarization-dependent generalized
differential cross sections (PDDCSs) and alignments of the product
rotational angular momentum are used to demonstrate the stereodynamics
effects. The rotational quantum number has a considerable influence on
the distribution of vector correlation, including alignment,
orientation, and PDDCSs. The product molecules are strongly forward and
backward scattering and weakly sideway scattering because the reactant
molecule HCl is in the rotational ground state and the lower rotational
excited states. Strongly forward scattering is observed while the
reactant is in high rotational excited states.%
