Found in nmr chemical shifts of common laboratory solvents as trace impurities by gottlieb, kotlyar, and nudelman have been an invaluable resource for synthetic chemists to identify residual solvents, e.g., et 2 o or thf, in research samples. The second group of protons giving signal in this region is the ones bonded to heteroatoms such as oxygen and nitrogen. There are two tables grouped by frequency range and compound class. 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: At the end of the workshift, wash any areas of the body that may have contacted diethyl ether, whether or not known skin contact has occurred.

The second group of protons giving signal in this region is the ones bonded to heteroatoms such as oxygen and nitrogen.
An ether may be a product of the condensation of alcohols. Here we present the nmr shifts of the most commonly used solvents and impurities in organic synthesis measured in the 7 most frequently used. 7 an expansion of these data tables to include gases and deuterated * on skin contact with diethyl ether, immediately wash or shower to remove the chemical.
