The dielectric behaviour of liquid and solid phases of cyclopentanone, cyclohexanone, cycloheptanone and cyclodecanone has been investigated at frequencies below 300 kcps. It has been found that cyclopentanone and cyclodecanone show a very sharp decrease of the dielectric constant at the melting point. Both, cyclohexanone and cycloheptanone show two solid phases of different dielectric behaviour, the ones existing just below the melting point have high dielectric constant and probably free dipole orientation.
