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
