We have employed deuterium NMR techniques to determine the dynamics of trimethoprim (TMP) in a binary complex with dihydrofolate reductase (DHFR) or in a ternary complex with DHFR and cofactor NADP+ in the fully hydrated state. TMP was deuterated at the following positions: (2',6'-D2)TMP, (3'-Ome-D3

## Abstract A detailed study on the deuterium NMR of hydrated collagen in the presence of alkali and alkaline earth salt is reported. The effect of different salts in reducing the deuteron quadrupole splitting are similer at low molar content of salt. At higher salt contents, larger ions are more e
