Abstract
The method of Gillan for solving the Ornstein-Zernike equation is applied to the SSOZ equation. Solutions are obtained for complex molecular models which represent CCl4, N2/O2 and CO2/ethane liquids. The peculiarities resulting from the extension of Gillan's algorithm for the description of these fluids are discussed. Site-site correlation functions are obtained and the calculated internal energy shows good agreement with computer simulation results.
