The stereodynamic properties of the reaction N(4S)+NO(X2Π)→N2(X3Σg-)+O(3P) in different initial reagent rotational states are studied theoretically by using the quasiclassical trajectory method on two lowest 3A" and 3A' potential energy surfaces at a collision energy of 0.6 eV. The vector properties of different rotational states on the two potential energy surfaces are discussed in detail. The results indicate that the rotational excitation of NO has a considerable influence on the stereodynamic property of reaction occurring on the 3A' potential energy surface, which can be ascribed to the early barrier on this potential energy surface.
