Abstract
From Raman and dielectric measurements on NaClO3 a solid-to-solid phase transition seems possible with the extrapolated transition temperature above the melting point (537 K) at normal pressure. By measuring the 35Cl nuclear quadrupole resonance as a function of temperature and using the Bayer theory we followed the temperature dependence of the chlorate ion's torsional frequencies. Comparison with the Raman data shows that these frequencies do not correspond to the presumptive soft mode, appearing in the Raman measurements.
