| Abstract: | The molecular structure of trans-stilbene has been studied by the gas electron diffraction method. Unlike the approximately planar structure with Ci symmetry found for the solid state, the molecule in the gas phase was found to be non-planar and to possess C2 symmetry. The phenyl groups were found to be rotated ca. 30° about the C-φ bonds. The non-planarity of the molecule is, however, not so large as to seriously influence the resonance energy. |
