Abstract
Low frequency dielectric investigations of disordered trimethylammonium cations are presented and discussed. Ordering process of N(CH3)3H+ cations are described by means of an asymmetry of doubleminimum potential. Pyroelectric experiment on TMACA provided clear evidence of another continuous phase transition at 127 K between two ferroelectric phases connected most probably with a motion of CH3 groups.
