Abstract

The ¹H spin-lattice and spin-spin relaxation times, and the second moment of the ¹ H NMR linewidth of choline perchlorate,[(CH₃)₃NCH₂CH₂OH]CLO₄ were measured in its highest-temperature solid phase, i. e. above 275 K. X-ray powder patterns taken at ca. 380 K revealed that in this phase the crystal has a CsCl-type cubic structure (a = 6.326(4) Å and Z = 1). From ¹H NMR experiments it was found that the cations in this phase undergo isotropic rotation and translational self-diffusion. From the ¹H T| measurements, the activation energies of the cationic rotation and self-diffusion were evaluated to be 21.4 ± 0.4 and 62 ± 3 kJ mol^-1, respectively.
