Abstract
Infrared and Raman measurements of lattice vibrations in hexagonal Mo have been made over the combined range 20-4000 . Two infrared-active modes at 384 and 470 and three Raman-active modes at 287, 383, and 409 have been observed. Classical dielectric oscillators are fitted to the reflectivity data, which are also analyzed by means of the Kramers-Kronig relations. The degeneracy of the and modes is interpreted as indicating that the layer-layer interaction is weak. All 15 optical modes are assigned to irreducible representations and their frequencies tabulated or predicted.
