Switched angle spinning

Among spatial reorientation techniques, one can find MAS, OMAS, variable angle spinning (VAS) and switched angle spinning (SAS) techniques. Mechanical spinning of LC materials, which has dated back to the early seventies,63,64 can control the averaging of anisotropic spin interactions... [Pg.85]

There have been a number of publications on correlation or separation experiments involving quadrupolar nuclei. Using switching angle spinning (SAS), the correlation of quadrupolar and chemical shift interactions between the two spinning axes can be established to extract the quadrupolar and chemical shift tensors as well as their relative orientations.199... [Pg.82]
