The motions of the ethylammonium ion in solid ethylammonium chloranilate, C2H5NH3 QHO4CI2, are studied by ‘h NMR second moment (M2) and spin-lattice relaxation time (Ji) measurements. Reorientations of the CH3 group about the C-C bond axis and the NH3 group about C-N bond axis were observed and their motional parameters were evaluated. The internal rotational barriers of the CH3 and NH3 groups of an isolated C2H5NH3 ion were estimated from ab initio molecular orbital calculations.
