A local model pseudopotential, depending on ionic and core radii and which incorporates the sd hybridization effects phenomenologically, is employed to calculate the phonon frequencies, liquid metal resistivity, binding energy, and the effective ion‐ion interaction of the noble metals Cu, Ag, and Au in conjunction with a dielectric function in the non‐interacting band scheme. Reasonably good agreement is found between the computed and the experimental results.
