Abstract : This work is a contribution to the calculation of transport coefficients for nitrogen, hydrogen, Mars and Titan atmospheres plasmas. The calculation which assumes local thermodynamic equilibrium is performed using Lennard-Jones potential and simple combining rules for the potential parameters for neutral-neutral interaction. A discussion is made for the other interactions: neutral-charged, charged-charged and electron-neutral. The results are compared with those of published theoretical studies for a temperature up to 30000 K.
