Pressure-broadening coefficients for (12)C(16)O(2) lines have been calculated with a recent model derived from the Robert and Bonamy approach which leads to more accurate results than the previously used Anderson-Tsao- Curnutte model. Systematic calculations of CO(2)-CO(2), CO(2)-H(2)O, CO(2)-N(2), and CO(2)-O(2) 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.
