ELECTRIC POLARIZATION OF ONSAGER FLUIDS .2. BIREFRINGENCE .1. KERR-CONSTANTS OF PURE SUBSTANCES

The Kerr constants of pure liquid organic compounds, which exhibit wea k intermolecular interactions and possess widely varying electric, opt ical and polarizational molecular parameters, were computed from the d ata on dielectrometry and electric birefringence. Good agreement of th e calculated and observed values was reached as the result of the intr oduction of the local field model, which develops the concepts of reac tive field and local electric induction of a polarized fluid, into the orientational theory of the Kerr effect.
