High pressure inultinuclear magnetic resonance with electro-and superconducting magnets has been used to study the effect of pressure on the rates of fast solvent exchange reactions on tetrahedral, square-planar and octahedral metal complexes in aqueous and non-aqueous solvents. The most striking results were obtained for the divalent and trivalent high spin first row hexasolvated transition metal ions : for both series a gradual changeover in substitution mechanism occurs, with the early
