Theoretical principles and experimental details of the centerband-only detection of exchange ~CODEX! nuclear magnetic resonance ~NMR! experiment for characterizing slow segmental dynamics in solids are described. The experiment, which is performed under magic-angle spinning, employs recoupling of the chemical-shift anisotropy before and after a long mixing time during which molecular reorientations may occur. By an analysis in terms of the difference tensor of the chemical shifts before and… CONTINUE READING
