The vibrational relaxation of CO_2 in N_2 and CO has been studied by monitoring the infrared emissions from mode ν_3 of CO_2 and CO behind shock waves in the temperature range of 800-2500K. The experimental results are explained by the relaxation equation derived in terms of three main energy transfer processes: (1) CO_2 (ν_3)+B⇾Co_2(ν_1, ν_2)+B, (2) CO_2(ν_3)+B⇾CO_2+B, and (3) CO_2(ν_1, ν_2)+B⇾Co_2+B, where B=N_2 or CO. The rate constant for Process (1) has a temperature dependence in agreement with the theoretical prediction from the short range force theory, though its value is much larger than the theoretical one. The rate for Process (2) in collisions with N_2 shows a negative temperature dependence in a lower temperature region and a positive in a higher region, and a minimum is found in the vicinity of 1300K. While, the corresponding rate for CO has a weakly positive temperature dependence. These rate constants for Processes (1) and (2) can be connected smoothly to the data of the laser fluorescence measurements in the lower temperature region.
