    Broadening coefficients γ and interference coefficients ξ are calculated for different bands of the ammonia molecule in the case of line broadening by the pressure of argon and helium. A model intermolecular potential is used. It is shown that taking into account the interference effect changes the calculated values of γ, which suggests that the model potential parameters should be redetermined. The vibrational dependence of coefficients ξ is analyzed, and they are compared to coefficients ξ calculated for the same lines of the ammonia molecule pressure broadened by H2, O 2, N2, and NH3.
