Deuterated dichloromethane
WebDeuterated dichloromethane (CD 2 Cl 2) is a form (called an isotopologue) of dichloromethane (DCM, CH 2 Cl 2) in which the hydrogen atoms ("H") are replaced … 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 .

WebIn this paper we present a study that addresses the role of hyperfine couplings via the EPR and DNP measurements on some selectively deuterated BDPA radicals synthesized for this purpose. Newly developed synthetic routes enable selective deuteration at orthogonal positions or perdeuteration of the fluorene moieties with 2 H incorporation of >93%.

WebDec 14, 2024 · The resulting complex [B 10 H 9 CO⋅H fac] 0 is stable in dichloromethane CH 2 Cl 2; however, after several days of exposure at room temperature, destruction processes with opening of the closo-cage are observed.This behavior is very different from the protonation of the closo-decaborate anion [B 10 H 10] 2– with … 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.
