WebAll deuterated solvents must be handled in a strict anhydrous and inert atmosphere (dry nitrogen or argon) in order to minimise the absorption of moisture. This absorption leads not only to an increase in the HDO concentration and the resultant signal in 1H NMR spectrum, but also to an exchange of the easily labile protons (especially heteroatom-linked protons).
