Abstract
The acoustic absorption in mixtures of CO2 and O2 has been measured for 90%, 80%, and 70% concentrations of O2 at 300 °K. The absorption has been analyzed to extract the rate of energy transfer between the vibration of the bending mode of CO2 and the O2 vibration and the rate at which O2 de-excites the bending mode of CO2 in a v-t process. The rate constants for the v-t de-excitation of the bending mode of CO2 by O2 was found to be about the same as de-excitation by CO2. The v-v exchange between CO2 and O2 increases only slightly from 1.6 × 105 (sec atm)−1 at 300 °K to 2.5 × 105 at 600°K.
