Raman spectroscopic studies of MX2-type layered compounds
WebbThe conclusion is thus reached that the Born lattice dynamics does not correctly picture the vibration spectrum of the rock-salt lattice. On the other hand the observed facts, both in respect of Raman effect and infra-red absorption, fit into the theoretical picture provided by the dynamics of crystal lattices recently worked out by Sir C. V ... WebbRaman Spectra and Lattice Dynamics of Tellurium. Pine, A. S. ; Dresselhaus, G. The Raman spectrum of trigonal tellurium has been obtained at 295 and 90 °K. The Raman-active A 1 singlet and two E doublets are identified by the scattering polarization selection rules, and the E-mode LO-TO splittings and linear wave-vector shifts are observed. alberto dogliani
