NMR Consequences of the Nucleus–Electron Spin Interactions

This chapter introduces the readers to the principles of paramagnetism and to the effects of paramagnetism on NMR spectra. It provides an in-depth review of the equations describing the hyperfine shifts, composed of the contact and pseudocontact contributions, the paramagnetism-induced partial self-alignment and the subsequent paramagnetic residual dipolar couplings, and the paramagnetic relaxation enhancements to the nuclear relaxation rates. The dependence of these effects on the selected paramagnetic metal ion is also discussed.
