The "Ne NMR spectrum of Z'Ne-enriched neon gas dissolved in the anisotropic phase of the thermotropic liquid crystal ZLII 167 was recorded at various temperatures. The curve obtained by plotting the absolute value of the quadrupole coupling constant, 1x1, as a function of temperature is found to pos
