Dielectric dispersion is shown to occur at radio-frequencies in single crystals of [4-NH 2 C 5 H 4 NH][SbCl 4 ] in the frequency range of 200 Hz–1 MHz. It is found that dielectric dispersion, measured in the incommensurate phase (270.5–304 K) along the [102] direction of the monoclinic symmetry, is monodispersive, except for the close vicinity of T c =270.5 K, for T < T c +1 K. In the incommensurate phase (for T > T c ) the apparent critical slowing down is found with τ≈1×10 -4 s just above T c .
