Neutron measurements of the low energy phonons in relaxor ferroelectric (1-x) Pb(Zn 1/3 Nb 2/3 )O 3 -xPbTiO 3 (x = 0-15%) show lattice dynamic connecting to diffuse scattering. In (200) zone, where there is no observable diffuse scattering, the effect of the diffuse on phonons is expected to be minimal. A comparison of the scattering in this zone to that in (110), where significant diffuse is present, reveals strong coupling of the diffuse component to the acoustic mode.
