WebApr 8, 2024 · The polarizing agents AMUPol and TOTAPOL have been investigated before in the context of biological assemblies using 10 percent deuterated DMSO. [54] In general, DNP MAS NMR at 100 K has the further advantage that the low temperature prevents changes in the sample during measurement, [47], [48] which is important here to prevent … WebCommon solvents include chloroform-D, acetone-D6, benzene-D6, deuterium oxide (D 2 O), DMSO-D6, ethanol-D6, and methanol-D4. Other, less common deuterated solvents can be ordered through Chemistry Stores from Cambridge Isotope Laboratories or Sigma-Aldrich/Isotec . Typical NMR samples contain 0.6-0.7 mL of deuterated solvent.
Pure deuterated DMSO shows no peaks in H NMR spectroscopy and as a result is commonly used as an NMR solvent. However commercially available samples are not 100% pure and a residual DMSO-d5 H NMR signal is observed at 2.50ppm (quintet, JHD=1.9Hz). The C chemical shift of DMSO-d6 is 39.52ppm (septet). WebMar 27, 2024 · This study reports the residual 1H and 13C NMR chemical shifts of 42 green solvents, acids, and bases in eight NMR solvents, namely, dimethylsulfoxide-d6, chloroform-d, D2O, CD3OD, CD3CN, acetone-d6, tetrahydrofuran-d8, and toluene-d8. The multiplicities and coupling constants of 1H signals are also determined herein.
