The alkali hydroxides (MOH) and their corresponding deuteroxides (MOD), generally transform to electrically ordered phases below transition temperatures between 150 K to 310 K. The exception is NaOH, which exhibits no transition down to 6 K — an extreme isotope effect. The K, Rb and Cs hydroxides display a more conventional isotope effect, with MOD having a higher transition temperature than MOH by about 30 K.
