Abstract:

Results of calculations of line widths of 18 water vapor microwave lines broadened by N₂, O₂, CO₂, air, H₂O, CO₂, He, Ar, Kr, and Xe in the temperature range 30 ≤ T ≤ 400 K are presented. In the case of the broadening H₂O lines by monatomic gases, these results strongly depend on the chosen interaction potential; for T ∠∼ 100 K, they depend on the model of trajectories of colliding molecules. The comparison with experimental data and other calculations is given. The results can be useful for spectral calculations required by atmospheric applications.

Keywords:

broadening, H2O lines, temperature dependence, polar and monatomic gases
