摘　　要：基于多体展式方法所导出的N2 HF的分析势能函数 ,用准经典的Monte Carlo轨迹法研究了N2 HF(v′,J′)→N2 +HF(v″,J″)振转非弹性碰撞过程。结果指出 :N2 对HF的振动能级的粒子分布影响较大 ,在较低相对平动能下 。The non reaction dynamics of N 2+HF( v′,J′ )→N 2+HF( v″,J″) has been studied based on the analytical potential energy function of N 2HF using the quasiclassical Monte Carlo trajectory. It is reasonably found that the populations of rotational levels, particularly, for higher J values, are remarkably relaxed, and, it is effective for the vibrational levels of HF.
