KnowraAnharmonicityLinked fromLinked fromThe 9 pages that link to Anharmonicity, each with the reason it gives.All 9Related 7Compared with 2Infrared spectroscopyRelated: Real molecular vibrations show overtones and frequency shifts that the harmonic model cannot explain.PhononRelated: Anharmonic lattice forces let phonons interact and give finite thermal expansion.Molecular vibrationRelated: Real molecular vibrations depart from harmonic behavior, especially at high energies.Vibrational spectroscopyRelated: Real vibrations produce overtones and shifted energy levels that harmonic models cannot explain.Debye modelRelated: The harmonic Debye model omits thermal expansion and other effects caused by anharmonic vibrations.Einstein solidRelated: Real atomic vibrations are not perfectly harmonic, a limitation omitted by the model.Kopp's lawRelated: Temperature-dependent anharmonic effects can make measured heat capacities depart from simple additive estimates.
