RESIDUAL SOLVENT SIGNALS OF COMMON NMR SOLVENTS

TABLE 21. RESIDUAL SOLVENT SIGNALS OF COMMON NMR SOLVENTS 

TABLE 22. H NMR CHEMICAL SHIFTS OF TRACE IMPURITIES OF COMMON SOLVENTS AND REAGENTS 

Shaded region denotes residual undeuterated solvent. Multiplicities are singlet unless denoted otherwise (s=singlet, t=triplet, m=multiplet).. The multiplicities of trace impurities maybe different for methanol and ethanol if coupling with the OH proton is observed.
