Raman scattering has been used to study the vibrational spectra of GaSexS1-x layered mixed crystals at 10 K. We report the Frequency dependencies of different modes on composition x, with particular emphasis on A(1)('(2)) (A(1g)(1)) and A(1)('(4)) (A(1g)(2)) intralayer compressional modes having low dispersion in the Brillouin zone. The appearance of additional bands is attributed to multimode behavior typically exhibited by mixed crystals of anisotropic compounds.
