## Abstract Raman spectra of three polytypes of lead iodide (2H, 4H and 6H) have been investigated as a function of temperature at ambient pressure. The band assignments have been carried out on the basis of folding of 2Hο£ΏPbI~2~ phonon dispersion curves in the Brillouin zone. The temperature induce
Raman spectra of pressure-induced crystalline CHzBrz have been measured at room temperature for pressures up to 240 kbar in a gasketed diamond anvil cell. The pressure dependence of the internal and lattice modes are reported and discussed. A phase transition appears between 170 and 240 kbar. This h
