Nuclear magnetic resonance measurements have been made on proton in aqueous solution of paramagnetic ions by pulse method.
The ratio of spin-lattice relaxation time Tl to spin-spin relaxation time T2 of proton is about unity for Fe++, Ni++, Co++ and Cu++ solutions, however, it is 6.7 for Mn++ solution at about 8600 oersted.
Various methods of measuring T1 and T2 are described; multi-pulse method is used for T2 when self-diffusion of the solution is large.
