WebSep 7, 2024 · What is D2O exchange in NMR? This strategy is called D2O exchange or, more colloquially, the “D2O shake.” This exchange eliminates the OLH resonance (thus identifying it) and also eliminates any splitting between the a-protons and the OLH proton. The only splitting re- maining is then the splitting with any b-protons.
