Abstract

The molecular structure of gaseous phenol has been determined by electron diffraction. This has led to an accurate measurement of the internal ring angle at the place of substitution, α = 121.6° ± 0.2°, an important geometrical parameter that is hard to determine accurately by microwave spectroscopy or ab initio MO calculations. Comparison with solid state results suggests that the angle α decreases by about 1° in going from the free molecule to the crystal. This may reflect a change in the electronic properties of the OH substituent, caused by intermolecular hydrogen bonding in the solid state.
