WebD2O is used for example as cooling liquid in nuclear reactors, in medicinal diagnostics, in research and for NMR (Nuclear Magnetic Resonance) analyses. Introduction. Deuterium Oxide, also called "heavy water", has the chemical formula D 2 O. The deuterium atom, expressed by the symbol D, is a hydrogen isotope.
WebSep 7, 2024 · Why is D2O used in NMR? September 7, 2024 by Alexander Johnson. Explanation: Reason 1: To avoid swamping by the solvent signal. There is usually much more solvent than sample in an NMR tube. An ordinary proton-containing solvent would give a huge solvent absorption that would dominate the 1H-NMR spectrum.
