Abstract

The motions of the ethylammonium ion in solid ethylammonium chloranilate, C2H5NH+3 · C6HO4Cl-2, are studied by 1H NMR second moment (M2) and spin-lattice relaxation time (T1) measurements. Reorientations of the CH3 group about the C-C bond axis and the NH+3 group about C-N bond axis were observed and their motional parameters were evaluated. The internal rotational barriers of the CH3 and NH+3 groups of an isolated C2H5NH+3 ion were estimated from ab initio molecular orbital calculations.
