Temperature dependence of Raman spectra of ferroelectric liquid crystal MBOPDOB is examined in spectral region 0-30cm-1 with spectral emphasis on the quasielastic light scattering near solid-Sm C*transition.The quasielastic components are well fitted to Debye-type susceptibility function.With increase of temperature the inverse of the relaxation time T linearly goes to zero in the temperature range below the transition,manifesting a critical slowing-down.The relaxation time keeps same big value in the Sm C*phase as that at the transition point owing to long orientational relaxation in the liquid phase.
