Proton transverse relaxation rate of 17O-enriched water

Proton transverse relaxation rates of 17O-enriched water at pH in the neutral range were determined with isotopic compositions of 17O varying from natural abundance to 5%. Meiboom's account of the proton T-1(2) caused by the scalar interaction between the proton and 17O is generalized to accommodate new data. The generalized formulation covers 17O enrichment above the limit to which Meiboom and his co-worker constrained all their work.
