Deuterated dichloromethane
WebDeuterated methanol (CD 3 OD), is a form (called an isotopologue) of methanol (CH 3 OH) in which the hydrogen atom ("H") is replaced with deuterium (heavy hydrogen) isotope ("D"). [1] Deuterated methanol is a common solvent used in NMR spectroscopy . Deuterated methanol was first detected in interstellar space was Orion-KL in 1988 by scientists ... WebNotes on NMR Solvents. Most NMR spectra are recorded for compounds dissolved in a solvent. Therefore, signals will be observed for the solvent and this must be accounted for in solving spectral problems. To avoid spectra dominated by the solvent signal, most 1 H NMR spectra are recorded in a deuterated solvent.
