On the basis of a few realistic potential energy functions, expressions have been deduced for computing the anharmonicity of alkali halide crystals. An attempt has been made to estimate the magnitude of the anharmonic terms for the principal mode of oscillation of the crystal, that is the oscillation of the lattice of positive ions with respect to the lattice of the negative ions.
