The pressure broadening coefficients for 164 H2O lines calculated for the cases of air, nitrogen, and oxygen as foreign gases as well as self-broadening coefficients are presented. The Anderson-Tsao-Curnutte (ATC) technique modified to allow for intermolecular interactions and Maxwell distribution of molecules over the relative velocities was used in the calculations. A good agreement with experimental results has been obtained for all H2O lines considered. Comparison of results obtained by the ATC method and the method based on complex Robert-Bonamy formalism (CRBF) has shown that in the case of strong collisions both of these methods give close results.
