Bulk Viscosities of MBBA from Ultrasonic Measurements

  • K. A. Kemp
  • S. V. Letcher


The propagation of ultrasound in oriented nematic liquid crystals has been shown to be anisotropic.1–6 The attenuation and, to a lesser extent, the velocity of sound depend on the direction of propagation relative to the preferred molecular orientation direction. The hydrodynamic theory of Forster, et al.
