Nematic

It is easy to see, however, that the same coefficients in nematics determine the adiabatic deformations also.

For low-molecular-weight nematics, it has been known that the constitutive equation of nematics is entirely different from that for isotropic liquids.

Electrohydrodynamic instabilities in nematics could be classified according to the dependence of the threshold voltage (or field) on the physical parameters of the liquid crystal, cell geometry, field frequency, etc.
