The NMR spectrum of phenol, dissolved in a nematic solvent, is explainable in terms of two averaging planar structures for each of which the principle axis of orientation in the ring is on the opposite side of the oxygen atom from the hydroxyl proton. External hydrogen bonding to the solvent seems to be an important factor in determining the orientation. The molecular structure obtained is compared with those found by microwave spectroscopy and X‐ray diffraction.
