## 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 aminopyridi
## Abstract ^1^H and ^13^C NMR parameters of methotrexate in [^2^H~6~]dimethyl sulphoxide were obtained and analysed in terms of a βpreferredβ conformation. The effective correlation time of the anisotropic motion of the pteridinylbenzoyl moiety was evaluated as __ca__. 10 ns at 300 K. The ^1^Hο£Ώ^1^
