A study was made of the long-wavelength infrared reflection spectra of GaSe//1// minus //xTe//x solid solutions. The measurements were carried out in the spectral range 400-30 cm** minus **1 at room temperature with a resolution of at least 1 cm** minus **1. The frequencies of the transverse and longitudinal optical phonons were determined by analyzing the reflection spectra using the Kramers-Kronig relationship. It was found that the dependence of the phonon frequencies on the composition in the GaSe//1// minus //xTe//x system was of the one-mode type.
