摘要: Abstract The proton magnetic resonance spectra of polycrystalline triethylammonium halides [(C 2 H 5 ) 3 NH] + X − , = Cl Br I are obtained over the temperature range from 77 K to 470 K. From a comparison experimentally and theoretically estimated second moments, reorientations methyl groups, ethyl groups whole cation evidenced. results indicate that significant, or even main, contribution potential barriers derived for respective motional processes arises electrostatic interaction.
