Theoretical far-wing line shape and absorption for high-temperature CO2.
Theoretical results for the far-wing line shapes and corresponding absorption coefficients in the high-frequency wing of the nu(3) fundamental band of self-broadened CO(2) are presented for a number of temperatures between 218 and 751 K. These first-principles calculations are made assuming binary collisions within the framework of a quasi-static theory with a more accurate interaction potential than in previous calculations. The theoretical results are compared with existing laboratory data and are in good agreement for all the temperatures considered.
