The nuclear quadrupole interaction at181Ta on Hf/Zr-sites in ZrS2, HfS2, HfSe2, and HfTe5 exhibits anomalies as a function of temperature, indicative of lattice instabilities. We interpret our observations as being due to static or low frequency structural distortions perpendicular to the layers and take these as evidence for Ruelle's turbulent crystal.
