SPINNING SIDE-BAND FROM CHEMICAL-SHIFT ANISOTROPY IN C-13 MAS IMAGING

Solid state imaging by C-13 MAS imaging is described. The spinning sid ebands occurring at moderate spinning speeds, which disturb the images , can be suppressed by TOSS. For rigid solids the spatial resolution t hat can be achieved in this way is better than that of H-1 images at t he same spinning speed. Spatially resolved spectra with or without spi nning sidebands can likewise be recorded providing information about t he isotropic and the anisotropic chemical shifts which can be exploite d for the study of structure, order and dynamics. The techniques are d emonstrated on a phantom made with C-13-labelled glycine.
