Statistical mechanical theory for transport properties of molecular fluids

We present the statistical mechanical theory for transport properties of molecular fluids of non-spherical molecules interacting via the Gaussian overlap potential with constant energy (GOCE). The transport properties of the molecular fluid are expressed in terms of a hard convex body fluid of properly choosen hard sphere diameter. We divide the GOCE potential into the reference and perturbation parts according to the Weeks-Chandler-Andersen type scheme. The effective hard sphere diameter of the reference fluid is obtained through the blip function theory. The explicit expressions for the shear viscosity and thermal conductivity are given. The theory is applied for fluid N-2. The agreement with experimental results are found to be good.
