"A generalized Lyddane-Sachs-Teller relation is derived. The assumption that the lonic motion is described by a set of independent damped oscillators is relaxed, and the derivation is based simply on causality and energy conservation, plus the assumption that [E] has a finite number of poles and zeroes. The parameters appearing from that previously accepted, but they are more directly related to the observable quantities in neutron and Raman sacattering, and infrared experiments".
