Abstract

Pressure-broadening coefficients for 12C16O2 lines have been calculated with a recent model derived from the Robert and Bonamy approach which leads to more accurate results than the previouslyused Anderson-Tsao-Curnutte model. Systematic calculations of CO2–CO2, CO2–H2O, CO2–N2, and CO2–O2 broadening coefficients in the 300–2400-K temperature range are presented. The results are suitable for both IR and Raman lines and should be useful for spectra calculations. Tabulations of the broadening coefficients are given together with simple analytical expressions for their rotational quantum number and temperature dependences.
