Five schemes characterised by the nature of the interactions are developed on the lines of a recent model due to Fielek, which includes the interaction among all the constituents of a non‐simple metal. Equilibrium conditions are derived for each of the schemes. Volume interactions are described on the lines of a simple scheme which explains realistically phonon dispersion in non‐simple metals like palladium and nickel. These schemes are employed to explain cohesion, the Cauchy deviation, anisotropy, and phonon dispersion in the said metals. Overall standard errors of the mean percentage deviation are calculated to draw conclusions regarding the nature of the relevant interactions.
