Abstract The dielectric behaviour of 4‐n‐butyl‐4′‐n‐dodecyloxyazobenzene was investigated in the smectic A, C and I phases from 10 2 to 3 ṁ 10 6 Hz. In all phases a dielectric relaxation process could be found which is connected with the reorientation of the molecules around their short molecular axes. At the phase transition S C /S I a step of one decade was observed in the relaxation frequencies.
