The viscosity-dependent retarding effect of a polymeric solvent The rotational tumbling with the correlation time t c acts as on the rotation of small solute molecules is investigated by 13 C a multiplicative ''masking'' process of the intramolecular NMR relaxation measurements. It is found that the
The NMR relaxation times of the "C(O) nuclei of formanilide, acetanilide, benzamide, benzoic acid, the benzoate anion and glycine were measured for four different magnetic field values, allowing the determination of the contribution of the shielding anisotropy mechanism to the total relaxation rate.
## Abstract It is demonstrated that in a case where neither the proton nor the naturalβabundance ^13^Cβsatellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
