摘要：

Solution NMR spectroscopy of nucleic acids has been limited by the short-range nature of the nuclear Overhauser effect and scalar coupling restraints normally used in structure determination. The addition of residual dipolar couplings, obtained from slightly oriented mixtures, provides bond vector angles relative to a universal alignment tensor. The accurate determination of helix curvature, domain orientation and the stoichiometry of homomultimeric nucleic acid complexes is now possible.
