摘要：

A novel method for water signal suppression in H-1 NMR spectra is proposed for biological systems. It is based on the acquisition of a spin-echo spectrum in the presence of Dy(III) complexes, which cause a marked decrease of the water proton T2 through the modulation of DELTA-omega-M (chemical shift difference between the bulk and coordinated water resonance) by tau-M (time associated with the exchange between the two sites).
