The trajectory calculations of the reaction Sr＋HF on the extended LondonEyring PolanyiSato (LEPS) potential energy surface have been carried out to study the dependence of product rotational alignment on the collision energies. The calculated results for the reaction of Sr＋HF were compared with the predictions from the constrained product orbital angular momentum model. The final rotational angular momentum was found to be perpendicularly polarized with respect to the reagents′ relative velocity vector. The higher the collision energies are the more anisotropic is the distribution of the product rotational angular momentum vector.
