Abstract
We present a study of the phonon properties of the CuP2-like ordered GaInP2 compound within the adiabatic bond charge model. We discuss the folding re lations of the acoustic and optical modes and the angular variation of the optical modes. The calculated infrared response is compared with available experimental data. An analogous procedure is done for ordered GaInAs2 and a prediction for experimental data is made.
