The 1 H NMR spectrum of 1,4dimethylbenzene (pxylene), shown in Figure below, is a simple example that we can use to learn how to interpret chemical shifts First, note that there is a signal at δ 0Furthermore, a comparison with the 1 H nmr spectrum on the right illustrates some of the advantageous characteristics of carbon nmr The dispersion of 13 C chemical shifts is nearly twenty times greater than that for protons, and this together with the lack of signal splitting makes it more likely that every structurally distinct carbon atomNuclear Magnetic Resonance (NMR) Spectroscopy NMR Chemical Shift Values Table In the previous post, we talked about the principles behind the chemical shift addressing questions like how the ppm values are calculated, why they are independent of the magnetic field strength, and what is the benefit of using a more powerful instrument

55A The source of spinspin coupling The 1 HNMR spectra that we have seen so far (of methyl acetate and paraxylene) are somewhat unusual in the sense that in both of these molecules, each set of protons generates a single NMR signalIn fact, the 1 HNMR spectra of most organic molecules contain proton signals that are 'split' into two or more subpeaksNMR r 474 (Cp)5Hs, r 3 (H(3,4)) 2Hm, r 390 (H(2,5)) 2Hm, T 569 (H(1,6)) 2Hm, 718 (H(7) endo) iHm, 1010 (H(7) exo) iHm CpFe(~6CsH8)PF6 This compound was prepared by irradiating CpFe(pxylene)PF6 (573 mg) in the presence of cyclooctatetraene (724 mg) for 3 hours at 3 3 451 mg (79% yield) of orange crystalline CpFe(i~6CgH8)PF6Proton decoupling must be used to obtain good resolution in this phase and this is an indication for considerable dipolar interaction between the pxylene
