Resumen:
Observations are reported of inelastic light scattering from the non-zero wave vector soft phonon that drives the incommensurate structural phase transition In K2SeO4. They are shown to correlate with neutron scattering measurements of phonon frequency shifts on cooling to the Incommensurate transition temperature. Incommensurate transition temperature. The observed light scattering is suggested to arise from intrinsic disorder
