【 摘 要 】

We have studied a system of nematic quadrupoles interacting via inverse power potential of the form U ≈ (σ/r)5(σ is the diameter of the particles and r is the separation between them), both in 3-dimension and 2-dimension. Pair correlation function has been calculated by solving Rogers-Young (RY) integral equation theory. Thermodynamic consistency has been obtained ensuring the equality of pressure calculated by virial and compressibility routes.
