Abstract
Solvent effects on the NMR geometry of tellurophene due to correlation between vibration and rotation have been determined and corrected in various liquid crystals, resulting in a unique solvent‐independent structure. Simultaneously, the bond interaction parameters, which describe the torques acting on the bonds of the molecule in the anisotropic liquid crystal potential (giving rise to deformations and to the molecular orientation), have been measured. A linear relationship has been detected between the CH bond interaction parameters for tellurophene and for methane in the same solvents.
