Thermal diffusion factor was calculated for dipolar binary fluid mixtures modelled as a two-center Lennard-Jones plus point dipole using the non-equilibrium molecular dynamics simulation. Thermal diffusion factor was an increasing function of the dipole moments of two components in isotopic model mixtures. Thermal diffusion factor in dipolar fluids was also a sensitive function of the electrostatic part of the intermolecular interactions.
