Raman scattering spectra of ternary semiconductor alloys GaP/sub 1-//sub x/Sb/sub x/ and InP/sub 1-//sub x/Sb/sub x/ have been investigated in the spectral region from 150 to 450 cm/sup -1/ at room temperature. The optical phonons of both GaP/sub 1-//sub x/Sb/sub x/ and InP/sub 1-//sub x/Sb/sub x/ exhibit ''two-mode'' behavior over the whole composition range. A random element isodisplacement model is used to describe the behavior of the optical phonons of both alloy systems. The calculations of the dependence of the long-wavelength optical phonon frequencies on the composition are in good agreement with the experimental results.
