Born-Lertes effect on the dipolar rotation of liquids

  • E. Grossetti


We have determined the rotation moments of some polar liquids in a rotating electrical field for frequency values which are comprised between 0.325 MHz and 8.5 MHz. The noticeable differences we have found between the experimental values and the theoretic ones are been imputed to a change of conductivity and dielectric constant owing to the frequency change.


In questo lavoro sono stati determinati i momenti di rotazione di diversi liquidi polari in campi elettrici rotanti per frequenze da 0.325 a 8.5 MHz. Per alcuni di essi la diversità riscontrata tra i valori sperimentali e quelli teorici sta a significare una variazione della conducibilità e della costante dielettrica al variare della frequenza.
