Deuterated solvents are solvents that contain deuterium (D or ^2H), an isotope of hydrogen that has an extra neutron. In these solvents, some or all of the hydrogen atoms in the solvent molecule are replaced by deuterium atoms. This substitution alters the physical and chemical properties of the solvent, which can be beneficial in various applications, particularly in nuclear magnetic resonance (NMR) spectroscopy.
