Abstract
Abstract Proton magnetic resonance spectra have been studied over a wide temperature range for polycrystalline ethyltrimethylammonium halides [C2H3N(CH3)3]+X−, where X− = Cl−, Br− and I−. For the bromide and its ethyl-deuterated analogue, the proton relaxation times T1 were also measured vs. temperature. Analysis of the experimental data yields information on the activation parameters for molecular motion within the cation and of the cation as a whole. The potential barriers determined increase as anion size decreases.
