| Abstract: | Pressure-broadening coefficients for CO 2 molecule have been calculated with the infinite order sudden (IOS) approximation. Systematic calculations of CO 2-N 2, CO 2-CO 2 broadenting coefficients in the 296-1200K temperature range are presented. In these calculations, the modified Buckingham potential is used. It is shown that our calculated results are satisfactory and thus provide basic data for plume of high speed vehicles. |
