Abstract
A consistent treatment of the usual linear theory of lattice vibrations in ionic crystals without the use of the symplifying cyclic boundary conditions is shown to lead to an electric moment associated with each normal frequency which, like the frequency itself, is a quasicontinuous function of the propagation vector. As a result, a broadening of the line spectrum of elementary theory and additional absorption edges of apparently observable magnitude are predicted.
