    Abstract

    It was shown that the interaction potential for NH3-Ar and NH3-He systems is determined ambiguously from experimentally measured broadening coefficients γ of NH3 absorption lines. Different sets of model interaction potentials, given the same calculation accuracy of the coefficients of broadening by pressure of these gases at room temperature, determine these coefficients for other temperatures in different ways. This difference is the most pronounced for NH3 lines in a NH3-He mixture. For NH3 lines in a NH3-Ar mixture, this difference becomes apparent for lines with small rotational quantum numbers K; this effect weakens for K → J.
