ABSTRACT
The extension of integral equation and integral equation perturbation theories to molecular fluids was discussed in Chapter 4. Here, after outlining the general framework of the free energy perturbation theories for fluids with anisotropic interactions, several approaches to obtain the properties of different kinds of reference hard-body molecular fluids are described. The performance of these theories is discussed for a number of illustrative examples. This chapter continues with the description of a number of theoretically based approaches for the EOS of real molecular fluids and ends with a section devoted to the theoretical description of the nonisotropic phases and the related phase transitions.
