    Hyper-Raman scattering experiments suggest that a splitting of the lowest F1u-symmetry mode of PbMg1/3Nb2/3O3 crystal occurs in a wide temperature range around its Burns temperature Td. The lower-frequency component, known below the Burns temperature from far-IR spectroscopy, actually becomes underdamped above the Burns temperature.
