Abstract
The rate of vibrational energy transfer from CO2(001) to CO(v=1) has been measured from 730 to 2325°K using a shock tube. Time-resolved measurements were made of the infrared emission from the CO(v=1) level as it approached equilibrium following shock heating. These measurements were then used as input in a model calculation to obtain the rates for the CO2–CO energy-transfer reaction. The data indicate that energy transfer from CO2 to CO is slightly more efficient than transfer from CO2 to N2 in spite of the 10-fold increase in the energy defect for CO.
