Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents.

Calculated NMR spectrum (Predict Spectra via NMRDB) 1 H NMR Spektrum, 13 C NMR Spektrum. Percentage and isotopic composition: Mass-related elemental composition and isotope proportions of the compound Diethyl ether - C 4 H 10 O - calculated based on molecular mass.

Ether carbon atoms also exhibit a downfield shift in the 13 C NMR spectrum, where they usually absorb in the 50 to 80 δ range. For example, the carbon atoms next to oxygen in methyl propyl ether absorb at 58.5 and 74.8 δ. Similarly, the methyl carbon in anisole absorbs at 54.8 δ.

Figure 18.6 The 1H NMR spectrum of 1,2-epoxypropane. Ether carbon atoms also exhibit a downfield shift in the 13C NMR spectrum, where they usually absorb in the 50 to 80 δ range. For example, the carbon atoms next to oxygen in methyl propyl ether absorb at 58.5 and 74.8 δ .

For a molecule such as diethyl ether, CH 3 CH 2 OCH 2 CH 3, two types of protons would be predicted to appear in the NMR spectrum; a 'simple' CH 3 in the area of 1, and a CH 2 shifted down to about 4 by the electronegative oxygen.
