✦ Synopsis

An optical-optical double resonance technique has been used to study transfer between specific quantum levels in the A*TJ and X 'Z+ states of the CN radical in collisions with argon, Specific rotational levels within the v = 7 A state vibrational level are prepared by laser excitation m the A-X (7,2) band, while collisionally populated levels in this vibrational level and the nearly isoenergetic v = 11 level in the X state are probed by laser fluorescence excitation in the interleaved B-A (8,7) and B-X (8.11) bands. The collisional transfer rate from the relatively unperturbed N = 6 F, A-doublets to the X state is comparable to or faster than that for pure A -* A inelastic transitions. A significant alternation m the population of even versus odd N levels in the X state is observed, related to the near-homonuclear character of the CN-Ar interaction potentials.

The reaction C( 'P) +NsO(% \*C+) is studied by varying the kinetic energy of C(3P) in two center-of-mass regimes: 0.1-0.2 eV and 2-7 eV. C( 3P) is directly observed, and the C, velocity distribution is estimated from the time-of-flight of Cs. CN(X %+) is vibrationally inverted and rotationally 'hot'
