Protonic conductivities of cubic and monoclinic antimonic acids are known to depend on water vapor pressure. Their water sorption‐desorption characteristics are compared and discussed with the water sorption isotherms and the desorption spectra of H 2 16 O, D 2 O, and H 2 18 O. The cubic antimonic acid contains more water than the monoclinic acid, which can be attributed to the existence of micropores in the cubic (pyrochlore type) structure.
