Bulk Viscosities of MBBA from Ultrasonic Measurements
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.
