Sequential inversion recovery with RIDE-simultaneous suppression of two solvent signals in 17O NMR spectroscopy
Well-resolved 17O NMR spectra of D-mannopyranose in a mixture of solvents were obtained. The 17O NMR signals of DMSO and water have been successfully suppressed by incorporating two sequential inversion recovery steps, tuned to the relaxation of the two solvent signals, into the RIDE pulse sequence. The heights of the solvent signals are decreased by a factor greater than 1000. Copyright 1998 Academic Press.
