Description
The vibrational modes of hydrogen in (NH4)H5(PO4)2 have been investigated by inelastic incoherent neutron scattering at temperatures above (220 K) and below (160 and 5 K) the phase-transition point Tc = 180 K. Computer simulation of vibrational modes has been performed for the low-temperature phase (NH4)H5(PO4)2 at 5 K. The calculated generalized incoherent dynamic factor and the partial incoherent dynamic factors for all hydrogens make it possible to identify the observed modes from acid hydrogens and hydrogens of ammonium ions.
