Lyddane-Sachs-Teller relation

[lə′dān ′saks ′tel·ər ri‚lā·shən] (solid-state physics) For an infinite ionic crystal, the relation ε(0)/ε(∞) = ω_L²/ω_T², where ε(0) is the crystal's static dielectric constant, ε(∞) is the dielectric constant at a frequency at which electronic polarizability is effective but ionic polarizability is not, ω_Lis the frequency of longitudinal optical phonons with zero wave vectors, and ω_Tis the frequency of transverse optical phonons with large wave vector.
