Abstract Proteins, nucleic acids, and carbohydrates all show conforma-tional flexibility, but the extent is dependent on the structure and their environment. The motion in saccharides, in particular at the glycosidic linkage, defined by torsion angles and ª is of importance for molecular properties and biological function. Thus, the approximation of a single molecular structure is certainly an oversimplified picture. To obtain complete information about the molecular structure we desire to determine the conformational distribution function, P(,ª). Analysis of molecular conformations has for a considerable time relied on either the nuclear Overhauser effect (NOE), spin-spin (J) couplings, or a combination of these two. Recently, the application of dilute liquid crystalline phases (bicelles) as solvents enabled a slight net orientation of nonspherical “solute ” molecules and therefore determination of through-space magnetic dipole-
