RATE-CONSTANT FOR QUENCHING OF CO2(010) BY ATOMIC OXYGEN

The rate of quenching of CO2(010) by (O(P))-P-3 has been measured at r oom temperature by a temperature-jump method. The rate constant value obtained is in good agreement with a previous room-temperature measure ment based on steady-state analysis of a hollow-cathode discharge in C O2. The results of fitting the room-temperature result to trajectory c alculations with a curve-crossing (Nikitin) energy-transfer mechanism lead to the conclusion that the quenching rate constant should increas e only slowly with increasing temperature.
