www.orgchemboulder.comChapter 1: NMR Coupling Constants 2 Figure 1-2: The NMR spectrum of 1,1-dichloroethane, collected in a 60 MHz instrument. For both A and B protons, the peaks are spaced by 0.1 ppm, equal to 6 Hz in this instrument. This time, the peak spacing is 0.1 ppm. This is equal to a J constant of (0.1 ppm • 60 MHz) = 6 Hz, the same as before.

For CHD 2 groups (deuterated acetone, DMSO, acetonitrile), this signal is a 1:2:3:2:1 quintet with a splitting of ca.2 Hz. (3) In contrast to what was said in note 2, in the 13C spectra the solvent signal is due to the perdeuterated isotopomer, and the one-
