Name: The NMR spectra of the VO(acac)2 and Cu(acac)2 complexes are sharp and have small shifts but those of the Mn(acac)3 and Fe(acac)3 complexes are broad and have much larger shifts of 20 ppm (for the methyl groups). Suggest why there are large shift differences. Also, you will investigate the spectrum of the paramagnetic [Co(o-phenanthroline)3]Cl2 complex where the shifts are very much larger, as shown below. Figure 2 diamagnetic paramagnetic Suggest why this is. 100 80 60 40 20 0 fl (ppm)
