The fine structure in high-resolution NMR spectra produced by spin—spin coupling* between magnetic nuclei provides a very important source of information on the structure of complex organic molecules and the distribution of the electron cloud in them.

This chapter examines the magnetic interactions between nuclei, known variously as spin–spin couplings, scalar couplings, or J-couplings. Spin–spin couplings (J-couplings) give rise to multiplets in liquid-state nuclear magnetic resonance (NMR) spectra.

Abstract We now come to a second important aspect of high-resolution NMR spectra the fine structure. While the chemical shift is the main factor determining the frequency of the response from a particular chemical site, each response may also exhibit some fine structure representing interactions with neighbouring magnetic nuclei.

In most routine applications of NMR only the magnitude of the isotropic average of the coupling constant appears, and this merely as spacings in symmetric multiplet patterns. However, the additional information which comes from the sign of the isotropic average coupling constant and the anisotropy of the coupling tensor is of even greater use as a ...

Electron Spin Resonance: Spin Labels
1981In general biological membranes possess no intrinsic paramagnetism and hence in the unlabeled state do not give rise to an electron spin resonance (ESR) spectrum. The introduction of a stable free radical (“spin label”) thus enables one to use ESR spectroscopy to study specific environments within the membrane.
