Absorption of 9.6-μm CO2 laser radiation by CO2 at temperatures between 296 and 625 K has been measured at a pressure of 200 Torr. Experimental results for the R10—R26 and P10—P28 transitions have been obtained and compared with computed values of absorption. The relative optical broadening coefficients due to He and N2 have been measured on the R16—R22 and P16—P22 transitions over the same temperature range.
