The improper ferroelastic phase letovicite (NH 4 ) 3 H(SO 4 ) 2 has been studied by 1 H MAS NMR as well as by static 14 N NMR experiments in the temperature range of 296-425 K. The 1 H MAS NMR resonance from ammonium protons can be well distinguished from that of acidic protons. A third resonance ap
