This paper presents results of investigations of the Raman scattering of vibrational modes in Zn_{1-x}Mg_{x}Se crystals for the range of composition 0 < x < 0.43. The Raman polarized spectra of Zn_{1-x}Mg_{x}Se were measured at room temperature. The typical Raman spectrum shows four peaks which can be interpreted as longitudinal and transverse optical ZnSe-like and MgSe-like phonons. The ZnSe-like and MgSe-like vibrations can be described by the modified random element isodisplacement model. Results of the Raman measurements in the investigated range of composition confirm the two-mode behaviour of the optical phonons in the mixed Zn_{1-x}Mg_{x} Se crystals.
