13 C spin–lattice NMR relaxation rates of pyridine and 4‐,3‐ and 2‐aminopyridine were measured in CDCl 3 –DMF and water in the neutral and protonated forms. The relaxation data were analysed in terms of the existence of tight pairs of ions between chloride and protonated pyridine and aminopyridines and/or adducts with the solvent molecules in CDCl 3 –DMF.
