Abstract:

The dissociation kinetics of carbon monoxide diluted in argon and in mixtures of oxygen in argon have been investigated over the temperature range 8000 to 15,000K behind reflected shocks using light absorption at 1176 A. An induction period 5 to 100 times longer than the vibrational relaxation time of carbon monoxide was observed in the carbon monoxide-argon mixtures prior to the establishment of the steady state dissociation rate. Rate coefficients were determined for Ar, CO, and O as the collision partner, M. Induction time measurements obtained are in excellent agreement with the previous measurements of Fairbairn. Mechanisms are advanced to account for the measured induction behavior and steady-state dissociation rates. Author
