✦ Synopsis

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' at all collision energies. NO( X *II) is vibrationally much colder, but rotationally 'hot' at the higher collision energies. At lower energies, NO( X *l-I) has no vibrational excitation and is cold rotationally. Thus, little energy flow occurs between the 'old' NO and 'new CN bond, suggesting a predominantly direct reaction mechanism.
