Dissociative excitation of CH3NO2 by collision with He(23S) and Ne(3Po.2)has been studied respectively by observing CH(A2△→ X2п,B2∑→ X2п) andC2∑ → X2п and H (Balmer) (only in the He(23S)/CH3NO2 reaction) emissions in the beam apparatus under single collision. The emission rate constants of A - X, B – X and C - X of CH and H produced from the He(23S)/CH3NO2 reaction were determined by using the reference reaction method. The nascent vibrational distributions and rotational temperatures of CH(A) were determined through computer simulation assumming a Boltzmann rotational distribution. The dissociative process and the formation mechanism of CH(A) were studied, and a two-body dissociative process through an intermediate CH3* for CH（A）was suggested.
