Raman measurements between 77 and 340 K are reported for Ag 2 HgI 4 and Cu 2 HgI 4 . Additively far infrared reflection and transmission spectra between 30 to 180 cm −1 are measured. Symmetrybased vibrational band assignments are given for both the internal and external optic modes. The conductivity in the region 30 to 150 cm −1 is calculated and the behaviour is explained using the jump diffusion model.
