The observed degeneracy of mutually exclusive infrared- and Raman-active modes in Mo${\mathrm{S}}_{2}$ is traced by means of group theory to the weak van der Waals interaction between layers.

Infrared and Raman measurements of lattice vibrations in hexagonal Mo${\mathrm{S}}_{2}$ have been made over the combined range 20-4000 ${\mathrm{cm}}^{\ensuremath{-}1}$. Two infrared-active modes at 384 and 470 ${\mathrm{cm}}^{\ensuremath{-}1}$ and t

Crystalline lithium hydride, with four electrons per primitive unit cell, has the simplest electronic configuration of all ionic crystals with the sodium-chloride-type structure, and thus represents an excellent test case for existing theories of lat

Evidence is presented, based on Raman scattering measurements, that the three modes observed in the A1(TO) phonon spectrum of tetragonal BaTiO3 are first order. These results are interpreted as supporting the order-disorder model of the ferroelectric

Research interest in the phonon energies of layered crystal structures has grown rapidly during the last decade. The reasons for the interest vary from fundamental considerations concerning low-dimensional systems to the utility of these materials as
