Nuclear magnetic resonance suffers from an intrinsically low sensitivity, which can be overcome by dynamic nuclear polarization DNP. GdIII complexes are attractive exogenous polarizing agents for magic angle spinning MAS DNP due to their high chemical stability in contrast to nitroxide-based radicals. However, even the state-of-the-art GdIII complexes have so far provided relatively.

Theory of Electron Spin Resonance Bruce R. McGarvey Conference paper 164 Accesses Part of the Nato Advanced Study Institutes Series book series ASIC,volume 52 Abstract In this chapter we shall treat only the theory of transition metals and their complexes. 2.08.1 Introduction. Electron spin resonance ESR is a spectroscopic technique that detects the transitions induced by electromagnetic radiation between the energy levels of electron spins in the presence of a static magnetic field. Electron paramagnetic resonance EPR and EPR imaging EPRI are often used in the literature instead of ESR. Molecules with all electrons paired have no electron magnetic moment no EPR spectrum. Species that can be studied by EPR: free radicals transition metals with odd numbers of electrons or high spin excited states with S=0 e.g. triplet states EPR is magnetic resonance on unpaired electrons.

Electron Spin Two types of experimental evidence which arose in the 1920s suggested an additional property of the electron. One was the closely spaced splitting of the hydrogen spectral lines, called fine structure.The other was the Stern-Gerlach experiment which showed in 1922 that a beam of silver atoms directed through an inhomogeneous magnetic field would be forced into two beams.

In atomic physics, the electron magnetic moment, or more specifically the electron magnetic dipole moment, is the magnetic moment of an electron caused by its intrinsic properties of spin and electric charge. The value of the electron magnetic moment is approximately 9.284 764 10 24 J/T.

Abstract. We provide a review of current electron spin resonance ESR techniques for studying basic molecular mechanisms in membranes and proteins by using nitroxide spin labels. In particular, nitroxide spin label studies with high-field/high-frequency ESR and two-dimensional Fourier transform ESR enable one to accurately determine distances.
