Dielectric properties of n-pentyl-p-n-cyanobiphenyl in wide frequency range
Frequency dependence of the dielectric constant was measured for n-pentyl-p-n-cyanobiphenyl in the nematic phase. Two dielectric relaxations appear. The relaxation at high frequency is due to molecular motion; and the relaxation at low frequency is due to the ion drift, of which the relaxation time...

Conductivity due to ion drift can also be obtained from the imaginary part of the dielectric constant to be on the order of 10
