Magnetic interactions in

New (magnetic) interactions in the Hamilton operator due to electron spin. This destroys the picture of an orbital having a definite spin.

With an understanding of magnetic interactions in the solid state, inherent relaxation processes, and experimental techniques to overcome these difficulties, Schaefer et al. acquired the first liquid-like NMR spectrum of a solid by CP/MAS techniques [27]. Before a review of recent applications of CP/MAS NMR to the pharmaceutical sciences, the brief Experimental section details some important information regarding practical solid state NMR. 

The magnetic interactions in the reduced porcine and bovine enzymes are considerably weaker than in the oxidized forms. The temperature dependences of the intensity of the EPR signals afford an estimate of -7 and -5.5 1 cm l for the J values of the reduced porcine and bovine enzymes, respectively (73,81). The large shifts observed in the NMR spectra of both enzymes also indicate that the coupling is weak from the temperature dependence of the isotropic shifts, J is estimated to be ca. -10 cm i for reduced uteroferrin (81). By analogy to the proposed structure for semimetHrNs, the reduced enzymes would have a hydroxo bridge. 

CIDNP - is a nuclear resonance method based on the observation of transient signals, substantially enhanced in either absorption or emission. These effects are induced as a result of magnetic interactions in radical or radical-ion pairs on the nanosecond timescale. This method requires acquisition of an NMR spectrum during (or within a few seconds of) the generation of the radical-ion pairs. 

The canonical spin glass consists of a noble metal (Au, Ag, Cu, or Pt) diluted with a transition metal ion, such as Fe or Mn. The magnetic interaction in such systems is mediated by the conduction electrons, leading to an indirect exchange interaction—the RKKY (Ruderman and Kittel [70], Kasuya [71], and Yosida [72]) interaction, whose coupling constant J R) oscillates strongly with distance r between the spins as...
