title: Carbon-13 NMR relaxation study of the internal dynamics in cyclodextrins in isotropic solution.
abstract: (13)C nuclear spin relaxation processes in seven cyclodextrins (from six-membered alpha to twelve-membered eta) were investigated in (2)H(2)O solution at multiple magnetic fields. Detailed analysis of (13)C longitudinal relaxation in laboratory and rotating frames and (13)C{(1)H} nuclear Overhauser enhancement in these molecules yielded their rotational diffusion tensors and a semiquantitative picture of their internal dynamics.
