✦ Synopsis

The CH A *a-X * II emission was observed in the flowing afterglow reaction of charged species of argon with CHq. Energetic considerations show that metastable argon ions, A~+M~D, 4F, *F, *G), are piausl%le candidates, although the contribution of AZ= cannot be completely excluded. The CH A *A-X*II spectrum was analyzed; the ratio of vibrational poputations for the U' = 0 and 1 states, P&v' = l)/Pv&( U' = o), is estimated to be 0.56 f 0.17. and the effective rotational temperatures are (3.0 f 1.5) X lo3 and (1.7 + 0.4) X LO3 K, respectively.
