Deactivation Dynamics Of Carbon Dioxide In Gas Phase At Thermal And Moderately High Temperature Regimes

In this work we present a set of state-specific rate coefficients of processes of translational and vibrational energy exchange involving the asymmetric stretching mode of CO2 molecules in gas phase. Vibration-Translation exchange is studied from thermal up to moderately high temperature regime (4000 K). For the Vibration-Vibration exchange the first ten asymmetric stretching energy levels are covered at room temperature. Rate coefficients are obtained simulating the collision dynamics by a full dimensional intermolecular potential obtained in a previous work. The data are intended for use in the kinetic modeling of gaseous mixtures containing CO2 as a major component.
