“extra peaks” in a variety of commonly used NMR solvents, in the hope that this will be of assistance to the practicing chemist. Experimental Section NMR spectra were taken in a Bruker DPX-300 instrument (300.1 and 75.5 MHz for 1Hand13C, respectively). Unless otherwise indicated, all were run at room temperature (24 ( 1 °C).

NMR spectra were measured in deuterated solvents (Deutero.

Notes on NMR Solvents. I. Introduction. 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.

Pure deuterated DMSO shows no peaks in 1H NMR spectroscopy so is commonly used as an NMR solvent. However commercially available samples are not 100% pure and a residual DMSO-d51H NMR signal is observed at 2.50ppm (quintet, JHD=1.9Hz). The 13C chemical shift of DMSO-d6 is 39.52ppm.

Deuterated DMSO is a common solvent used in NMR spectroscopy. Deuterated DMSO is produced by heating DMSO in heavy water (D2O) with a basic catalyst such as calcium oxide. The reaction does not give complete conversion to the d6 product, and the water produced must be removed and.

Microscale NMR tubes are available with their construction optimized for various solvents including D20, CDCI3, DMSO-d6, and CD3OD and for probe type, RT probes or Cryoprobe™. These tubes allow for.

1. All the CIC NMR data is being saved directly to the casfsa.bu.edu server. Each instrument has its own share on the server. On the NMR host computers, the data will appear on the shares that were.

●The 1H spectra of the residual protons and 13C spectra were obtained on a Varian Gemini 200 spectrometer at 295°K. The NMR solvents used to acquirethese spectra contain a maximum of 0.05% and 1.0% TMS (v/v) respectively. Since deuterium has a spin of 1, triplets arising from coupling to deuterium have the intensity ratio of 1:1:1.

Pure deuterated DMSO shows no peaks in 1 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-d 5 1 H NMR signal is observed at 2.50ppm (quintet, J HD =1.9Hz). The 13 C chemical shift of DMSO-d 6 is 39.52ppm (septet).
