Using switched angle spinning to simplify NMR spectra of strongly oriented samples

A method that manipulates the alignment director of a liquid crystalline sample to obtain anistropic magnetic interaction parameters, such as dipolar coupling, in an oriented liquid crystalline sample is described. Using a complex switched angle spinning (SAS) method that involves three changes in spinning axis, the solidlike spinning sideband pattern are correlated with the isotropic chemical shifts in a 2D experiment.
