      It is easy to see, however, that the same coefficients in nematics determine the adiabatic deformations also.
    • 1988, Masao Doi, The Theory of Polymer Dynamics, page 368,
      For low-molecular-weight nematics, it has been known that the constitutive equation of nematics is entirely different from that for isotropic liquids.
    • 1996, Lev M. Blinov, Vladimir G. Chigrinov, Electrooptic Effects in Liquid Crystal Materials, page 274,
      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.
