Notes:
A novel method for water signal suppression in 1H 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 ΔωM (chemical shift difference between the bulk and coordinated water resonance) by τM (time associated with the exchange between the two sites).
