Deactivation dynamics of carbon dioxide in gas phase at thermal and moderately high temperature regimes

Abstract

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.
