http://www.chem.ucla.edu/~bacher/General/30BL/NMR/deuterosolvents.html WebDeuterated chloroform is by far the most common solvent used in NMR spectroscopy. While dichloromethane and chloroform (trichloromethane) are both commonly used solvents that dissolve a wide range of other organic compounds, deuterated chloroform is more easily produced and much less expensive than deuterated dichloromethane . WebDec 1, 1992 · EXPERIMENTAL All non-deuterated solvents were distilled and dried over 3 A molecular sieves. Deuterated solvents were used without further purification. All solutions of CH2 C12 (CD2 C12) as a solute were prepared volumetrically. The intensity and position of bands were established for a dichloromethane concentration of 0.3837 mol dm-3 . canon beginner professional camera
