Abstract

The objective of one- or multiple-dimensional exchange spectroscopy is to probe fluctuations between different resonance frequencies a spin experiences. The exchange processes as well as the fluctuations of the resonance frequency can be of extremely different natures. The resonance frequency may vary for example due to
  • sites subject to different chemical shift

  • isomers with different chemical shift

  • environments of different magnetic susceptibility

  • anisotropic spin interactions in combination with different orientations in solidlike materials

  • positions in a field gradient
