WebHeavy water is basically used as a moderator in nuclear reactors to slow down the neutrons so that they are captured and become effective to bring about the fission reaction. The main reason why heavy water is used as a moderator is because it captures less neutrons than the normal water. WebJun 23, 2015 · There are three reasons why deuterated solvents are used in NMR spectroscopy. 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.
