    Abstract

    An analytical formula for approximation of the real parts of resonance functions in the pressure-broadening theory is proposed. The trajectories are computed from the isotropic Lennard-Jones (6-12) potential using ordinary equations of classical mechanics. The proposed analytical formula is a part of a power series of hyperbolic tangents th(z). The coefficients of this series are determined for the real parts of nine resonance functions. A test calculation of broadening coefficients for HCl in argon is discussed.
