Proton resonance line shape and spin-lattice relaxation time T. were measuredfor r>olvcrvstalline NH4H(CH2C]CO0)2 in ferro- and r>ara-electric rhases.Peculiar line shape and its temperature variation were ascribed to increasingtunnel splitting between the A and T symmetry levels in the librational groundstate of NHf ion from 15 kHz at 23 K to 20 kHz at 60 K. This increase corre-sponds to a decrease of rotational potential barrier (14.6 kJ mol =' at 0 K) and adecrease of the ferroelectric order. Deuteron resonance line shape and T. werealso measured for polycrystalline ND.D(Cl-I.ClCO0).. An extra line-widthbelow T. was proportional to (T.-T)""""'. An activation energy of NH: andNDF reorientation above the transition point, 10.9 kJ mol -', was deduced fromthe T. data.
