Different models for conformational equilibrium of 2,2′-biselenophene have been examined in order to reproduce the DHH and DSeH direct dipolar couplings obtained by NMR spectra using liquid crystal solvents. The results allow the rigorous exclusion of various conformational possibilities and confine the conformation to an equilibrium between two twisted conformers, the transoid one being the more abundant. © 1979.
