✦ Synopsis
We present a study of solutions of the site-site Omstein-Zemike equation in the hypemetted chain (HNC) approximation (the extended RISM equation) in the critical region for diatomic fluids modeled with site-site 12-6 potentials and point charge dipoles. The results exhibit anomalies beyond those found in the HNC approximation for atomic fluids. For small bond lengths isotherms of the bulk modulus show considerable asymmetry with respect to the critical density and for some temperatures a local minimum at high density. For systems with large bond lengths the results are similar to those for atomic fluids.
