Analysis of the data on spontaneous emission probabilities and collisional broadening cross sections of 0001–1000 lines of the CO2 molecule

A critical analysis is made of the experimental values of the Einstein coefficients A_mn and of the collisional broadening cross sections of the P(20) line due to the 00⁰1–10⁰0 transition in the CO₂ molecule. On the basis of this analysis it is recommended that the A_mn = 0.187 sec^–1 value be used for the P(20) line and that the broadening of the lines at 300°K due to collisions of the CO₂ molecules with CO₂, N₂, and He be described by the constants 7.58, 5.56, and 4.86 MHz/Torr, respectively.
