The article presents a study which examines the highly disordered crystal form of triammonium hydrogen disulfate, NH4)3H(SO4)2 or (TAHS), in the high-temperature phase I. The study performed single-crystal neutron diffraction experiments to TAHS crystals, which were produced from aqueous solution through slow evaporation. Results show that all hydrogen (H) atoms except H3 show enlarged anisotropic mean-square displacements.
