The determination of the three-dimensional structure of organic and biomolecular compounds by NMR spectroscopy usually involves the measurement of 3J coupling constants,[1] NOEs,[2] and cross-correlated relaxation [3] to obtain information about dihedral angles, distances, and projection angles, respectively. If interconversion of conformers takes place and is fast on the NMR time scale, NMR spectroscopic parameters for flexible parts of the molecule are motionally averaged. This effect is one of the main complications in the structure determination of nonrigid molecules and often prohibits the determination of the relative configuration of organic compounds.It has been shown that residual dipolar couplings (RDCs) can yield information complementary to that obtained from 3J coupling constants and NOE parameters also for organic compounds [4–10] and enable the assignment of relative configurations even in the presence of a limited degree of motion.[11–15] The problem of the joint treatment of an unknown configuration and conformational averaging when residual dipolar couplings are used in structure determination
