The frequencies and linewidths of five Raman-active modes in a GaS 0.75 Se 0.25 layered crystal have been measured in the 10-300 K temperature range and in the 10-380 cm --1 frequency region. We observed softening and broadening of the optical phonon lines with increasing temperature. The analysis o
