Abstract: We present results for the structure and thermodynamics of a polar fluid obtained from a recently developed theory which is based on the method of conditional distribution. Within the framework of the method the concept of the average force potentials is used to develop a truncation procedure for an arbitrary equation of the chain. A closed system of integral equations for the average force potential is formulated. The Helmholtz free energy, the pressure, structural properties and the static dielectric constant are calculated in terms of the binary distribution function. We compare our results with experimental data and find that the theory gives realistic results. Comparisons are also made for self-diffusion coefficients obtained from molecular dynamics simulations.
