Static Dielectric Studies of Some Nematogenic Compounds

Abstract

Static dielectric constant studies of three nematogenic compounds, viz., 4′-(hexyloxy)-4 biphenyl carbonitrile, 4′-(heptyloxy)-4 biphenyl carbonitrile and 4-isothiocyanatophenyl 4-pentylbicyclo (2,2,2) octane I-carboxylate, have been carried out and reported in this paper. The behaviour of the dielectric constants with temperature in these compounds have been explained in terms of the dipole moment.

Key Words:

• dielectric constant
• dipole moment
