ABSTRACT
Electric modulus spectra were used for the analysis of the static dielectric properties of liquid cycloalkanones: cyclobutanone, cyclopentanone, cyclohexanone, and cycloheptanone, studied in the temperature range from (243 to 313) K, and cyclooctanone, studied from (303 to 343) K. Odd even effects with respect to the number of carbon atoms in the molecular ring of the compounds were found in the static dielectric permittivity value and in the dipolar aggregation ability, represented by the Kirkwood correlation factor.
