Abstract: Optical phonon frequencies for IR active modes have been calculated for layered mixed crystals in the series Hf S₂₋xTex (0≤x≤2) using MREI-model. The model is simple and involves only two adjustable parameters. Various force constants and the values of local and gap modes have been reported. The model has been found to work reasonably well and the calculated values agree with the experimental values.
