Abstract

Rates for resonant vibrational and rotational energy transfer from the 001 state by CO₂ + CO₂ collisions have been measured. All data were obtained by double-resonance spectroscopy with CO₂ lasers in a 2.5-m absorption cell at 700 K. Results for rotation transfer include pumped-level relaxation and the response of other 001 levels with ΔJ up to 18. These data are compared with four relevant collision models via a 35-level rate equation analysis.
