Abstract

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 Δω_M (chemical shift difference between the bulk and coordinated water resonance) by τ_M (time associated with the exchange between the two sites).
