A molecular dynamics study was made of the high-temperature phase of this material. It was found that the estimated sulfate tetrahedra reorientation rate, and the rate and activation enthalpy of proton transfer were in reasonable agreement with experimental data; in spite of neglecting the effects of H bonds upon the dynamics of the host lattice.
