单次碰撞条件下NH_2(～A^2A_1,(0,9,0))转动非弹性碰撞

Rotational Inelastic Collisions of NH_2(A^2A_1(0,9,0)) under Single Collisional Condition 

在单次碰撞条件下 ,对NH2 (～A2 A1,(0 ,9,0 ) )的转动非弹性碰撞进行了详细的研究 ,包括不同转动能级、核自旋、及自旋分裂双重态的传能 ,直接得到了一些倾向性规则 。

The study on the rotational state to state energy transfer (RSET) of asymmetric top molecule NH 2 (AA～U 2A 1) (0,9,0) under molecular beam condition is reported in detail,including a systematic study of the relative population transferred as functions of initially excited quantum state, different Ka, nuclear spin,and even spin doublet. Some propensity rules were obtained directly, and the relation of the mechanism of RSET with EGL(energy gap law) and AMT(angular momentum transfer) was discussed.
