The Lyddane-Sachs-Teller relation is a physics construct that describes the relationship between a material\u2019s static and dynamic dielectric constant (i.e., values indicating a system\u2019s behavior in the presence or absence of an external electric field, respectively) and the vibrational modes of the material\u2019s crystal lattice (i.e., resonance frequencies).<\/p>\n<p>This construct, first introduced by physicists Lyddanne, Sachs and Teller in 1941, has since been widely used to conduct solid-state physics research and materials science studies.
