Functionalized Alkanes 70 2.09 05 1.57 1.69 56 0.97 1.65 In the nmr spectrum of the dianion, the innermost methylene protons (red) give an nmr signal at +22.2 ppm, the adjacent methylene protons (blue) give a signal at +12.6 ppm, and the methyl protons (green) a signal at +5.6 ppm. Conjugation of a double bond with a carbonyl group perturbs the carbon resonances of both groups. Below are the main regions in the 1 H NMR spectrum and the ppm values for protons in specific functional groups: The energy axis is called a δ (delta) axis and the units are given in part per million (ppm). Most often the signal area for organic compounds ranges from 0-12 ppm.

RESULTS AND DISCUSSION 1H NMR spectral data for industrially preferred solvents in six commonly used NMR solvents (CDCl 3, DMSO-d 6,CD 3 CN, acetone-d 6,CD 3 OD and D 2 O) are provided in Table 1. Solvents in Table 1 were classified as either recommended II. NMR Solvent Signals The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table.
(ppm). NMR 1D Peaks Query Peaks are counted as a match if they are within .2 ppm for carbon and nitrogen atoms and if they are within .01 ppm for hydrogen atoms
