摘要：

In order to obtain information on the structural geometry of NH4HSeO4 near the phase transition temperature, the spectrum and spin- lattice relaxation time in the rotating frame T-1p for the ammonium and hydrogen-bond protons were investigated through H-1 MAS NMR. T-1p for the hydrogen- bond protons abruptly decreased at high temperature and it is associated with the change in the structural geometry in O-H ... O bonds. This mobility of the hydrogen- bond protons may be the main reason for the high conductivity.
