A symmetric treatment of the interaction between the radiation field and a diatomic ionic crystal with optical isotropy is presented; the explicit solutions of the problem can be readily obtained, which describe all the possible modes of vibration of the combined system of the radiation field and the ionic lattice. An unexpected conclusion is that the optical waves immediately below the infra-red dispersion frequency are in fact none other than what are normally considered as the transverse… 
Rotational Lattice Vibration in Complex Crystals:Part II. Vibrational Modes in Optical Branches and Interaction with a Conduction Electron
Under the assumption that the anionic radical may be regarded as a rigid symmetric rotor, both the translational and the rotational lattice vibrations in the optical branches, which may be excited in
Optical phonons in ionic crystals with a diatomic unit cell
Optical phonons in an ionic crystal with two atoms per unit cell have been considered. The equation of relative motion of oppositely charged sublattices has been derived with the use of the concept
Optical lattice vibrations in finite ionic crystals: I
A theory for the properties of long-wave optical vibration modes in finite ionic crystals of arbitrary shape is given. Neglecting retardation effects, it is found that in finite specimens there exist
Fabrication of the ionic-type phononic crystal and its long-wavelength optical properties
Abstract The ionic-type phononic crystal (ITPC) is composed of two kinds of ferroelectric or piezoelectric media with a periodic superlattice structure. Through the piezoelectric effect, there is the
Optical properties of an ionic-type phononic crystal
An ionic-type phononic crystal composed of two ferroelectric media with opposite spontaneous polarization aligned periodically in a superlattice structure was studied theoretically and experimentally to show that it can be used to simulate the microscopic physical processes in real crystals.
Polaritons in molecular crystals
The simultaneous propagation of lattice phonons and photons in molecular crystals is discussed. The equation of propagation of the modes involving molecular displacements and an electric field is
Infrared and Raman Spectra and lattice Vibrations of Some Ionic Crystals: Fluorides and Oxides
Abstract The infrared and Raman spectra of so-called ionic crystals have been subjects of many investigations by chemists as well as by physicists. These spectra have been interpreted on the basis of

We consider long-wave high-frequency upper phonon-polaritons and longitudinal optical phonons in diatomic ionic crystal. The model of free ions which are polarized in self-consistent electromagnetic
Optical phonons of small crystals
The long wavelength optical phonons of ionic crystals give rise to dipole-dipole forces, whose long range nature causes the vibrations to depend on the size and shape of the crystal sample. This


On the distribution of lattice vibrations of the KCl crystal
The distribution of characteristic vibrations of the KCl crystal has been calculated following Born, v. K\'arm\'an and Blackman under the assumption of both electrostatic and repulsive forces between
Messungen am Steinsalz im Ultraroten zur Prüfung der Dispersionstheorie
ZusammenfassungFrühere Untersuchungen über die Dispersion des Steinsalzes ziehen im wesentlichen nur die von der ultraroten Eigenschwingung entfernten Gebiete in Betracht, wo das Absorptionsvermögen

The interest in the frequency spectrum of the thermal vibrations in a crystal arose chiefly in connexion with the problem of the specific heat of crystals at low temperatures. Debye’s theory of the
