SOLVATION OF TITANOUS ION IN AQUEOUS AND METHANOL SOLUTIONS

The solvation of the titanous ion in aqueous and methanol solutions has been studied by means of proton, deuteron, and oxygen-17 magnetic resonance. Kinetic parameters for the exchange reaction of the solvent molecules between the coordination sphere and the bulk, hyperfine coupling constants, and relaxation times of the unpaired electron of the titanous ion have been determined. Attempts to interpret the results in view of the uniqueness of the titanous ion among the ions of the first transition-metal series have also been made.
