The rotational state distribution and velocity recoil of CO{sub 2} bath molecules excited to the asymmetric stretch ({nu}{sub 3}=2349 cm{sup {minus}1}) vibrational level by collisions with high energy NO{sub 2} molecules have been determined. The vibrational excitation process occurs with very little rotational or translational excitation of the CO{sub 2} and its probability is independent of NO{sub 2} internal energy over the range 22 200--16 600 cm{sup {minus}1}.
