Abstract
1H NMR spin‐lattice relaxation times and 2H NMR line shapes were measured in the low temperature phase of pyridinium iodide. The results are consistent with reorientation of pyridinium ions by 60° to populate secondary potential minima, 5.43 kJ/m above the favored orientation. This process, which constitutes the creation of orientational defects in the ordered phase, takes place by reorientation over a potential barrier of 14.6 kJ/m.Keywords
