Monosaccharide proton resonance spectrum

Another way of getting substantially the same result is based upon a homonuclear experiment to saturate selectively the chosen resonance under proton decoupled conditions. (202) The spectrum is again acquired under fully coupled conditions and thus is a complete coupled spectrum except that the multiplet from the saturated site is absent. This spectrum is subtracted from a normal fully coupled one to yield a trace that contains only the multiplet from the desired carbon. Full fine structure is displayed. Figure 27 shows the application of this method to the spectrum of the monosaccharide derivative...
