In comprehensive investigations the perturbation treatment of the Lebowitz equation with a square well attractive tail is utilised to calculate the partial and total structure factors at different atomic fractions of potassium in the potassium–rubidium melt. Further the Bhatia‐Thornton correlation functions are evaluated. Using the direct correlation function in the long‐wave limit, the isothermal compressibilities are calculated through the Kirkwood‐Buff equation. The partial structure factors are then utilised to calculate the self‐diffusion coefficients using the linear trajectory approximation due to Helfand.
