摘要：

The shapes of Q-branches in CO2 spectra in the 580-850 cm(-1) region for pure gas and mixtures CO2-He and CO2-Ar have been studied at resolutions up to 0.002 cm(-1). The branch broadening coefficients were measured in the pressure range from a few torr to 50 atm. Those for 11(1)02-02(2)01 Pi-Delta transition are different for pressures below and above 5 atm. At higher pressures the branch broadening coefficients are similar for all Q-branches. The observed Q-branch shape transformation is explained by line mixing effects.
