The paper reports dielectric measurements carried out for isatomalononitrile at different temperatures (346 to 383 K) and various frequencies (50 to 5 × 105 Hz). Kramers-Kronig relations are used to ascertain the magnitude of the dc conductivity and to enhance the reliability of dielectric measurements. The analysis of the results shows that there exist certain very slow dielectric phenomena in isatomalononitrile. The frequency dependent conductivity of isatomalononitrile increases approximately linear with frequency. The frequency exponent has the value of 0.5, independent of temperature. |
