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.

Two conformations of cis-cyclohexyl-10-crown-3 were detected in solution below 250 K using 1H NMR at 400 MHz and 13C NMR at 100 MHz. Chemical shift assignments were facilitated by spectra of two dideuterio derivatives. From relative peak area measurements, the conformation with the unit OÈCH 2 ÈCH 2
