This is extremely important in anisotropy in the REDOR experiment is also discussed. It is recomapplying the REDORTOSS method to study the structure of mended that nuclei with large chemical-shift anisotropies should a protein complex where the signal from the labeled rare be detected with the observable channel and the REDORTOSS spin is normally very weak, and any residual overlapping method used to eliminate the sidebands.
