✦ Synopsis

Proton transverse relaxation rates of '70-enriched water at pH in the neutral range were determined with isotopic compositions of "0 varying from natural abundance to 5%. Meiboom's account of the proton T;' caused by the scalar interaction between the proton and I7O is generalized to accommodate new data. The generalized formulation covers 1 7 0 enrichment above the limit to which Meiboom and his co-worker constrained all their work.

## Abstract ^17^O‐enriched acetic acid (2.5% in ^17^O) was synthesized by hydrolysis of acetic anhydride with ^17^O‐enriched water. The reaction was monitored by ^17^O and ^1^H NMR spectroscopy. Acetic anhydride, ^17^O‐enriched in both the ether and the carbonyl oxygens, was observed as an intermed

NMR imaging provides excellent soft tissue contrast which arises primarily because of the heterogeneous distribution of tissue relaxation times T I and T 2 . As a result, NMR has the potential for in vivo tissue characterization based on measurements of these relaxation properties, but there are sti
