Force constants for sodium are calculated on the basis of a formulation presented by White some years ago. The force constants are taken to be the sum of the three contributions from overlap repulsive forces, the Coulomb interaction between ions, and the ion-electron-ion interaction. The Slater-Koster formalism is used to estimate the electronic contribution. The calculated force constants agree fairly well with the experimental values obtained by Woods and co-workers. The results are discussed.
