http://chem.ch.huji.ac.il/nmr/software/thermometer.html 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).
