Wide line nuclear magnetic resonance studies of pyridinium hexafluorophosphate, chloride, and nitrate show line width and second moment transitions which are attributed to reorientational motions of the pyridinium ring. The differences in transition temperatures are due to the different hydrogen bonded structures in the three salts.
