The mixed crystal system KCl(1-x)Br(x) shows a one-mode type behavior. The variation of the long-wavelength transverse optical (TO) mode frequency at 1 atm pressure can be understood in terms of the virtual crystal model. The variation of the frequency with pressure or the mole fraction x can be expressed in terms of volume change alone. The slopes of the vTO mode vs P are highest for the end numbers, and are less for intermediate values of x, and may be understood in terms of a nonlinear variation of the compressibility with x.
