Abstract

Two models: (i) (n-6) Lennard-Jones (LJ) potential and a (ii) Lennard Jones Temperature Dependent Potential (LJTDP) were used for the determination of the intermolecular interaction potential parameters (PP) and simultaneous approximation of the measured experimental thermophysical properties (pVT and acoustic second virial coefficients B and b, and viscosity h) for gaseous chlorine (Cl2). A comparison of the results shows slightly smaller deviations between measured and calculated data for LJTDP calculations compared to the (n-6) LJ potential. This unessential priority of the LJTDP is compensated by the simplicity of (n-6) LJ potential, which we recommend for calculations of different potential dependent properties. We give tables with recommended data for of B, h, and self diffusion rD, produced in the temperature range 200-900 K, which are convenient for inter- and extrapolations..
