Conventionally this is the signal of the compound tetramethylsilane (tms). In other words, frequencies for chemicals are measured for a 1 h or 13 c nucleus of a sample from the 1 h or 13 c resonance of tms. 1.90 and 8.44 ppm, respectively). Return to nmr home page. 1h nuclear magnetic resonance (nmr) chemical shifts. It is widely used as a solvent and to manufacture other chemicals. Here we present the nmr shifts of the most commonly used solvents and impurities in organic synthesis measured in the 7 most frequently used. Anhydrous diethyl ether was dried via distillation of solvent containing sodium wire. The chemical shift of the ch3 protons in diethylether is δ = 1.16 and that of the ch2 protons is 3.36. The solvent chemical shifts3 were obtained from the spectra containing the solutes, and the ranges of chemical shifts (1) for recommendations on the publication of nmr data, see: Diethylether chemeical shift / diethylether chemeical shift / diethyl ether an overview.
