Abstract:

The study on the rotational state to state energy transfer (RSET) of asymmetric top molecule NH 2 (～A2A1) (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.

Key words: NH2 rotational state-to-state energy transfer, Propensity rule, Energy gap law, Angular momentum transfer
