conformations with shortintramolecular aryl–aryl contacts. Gas electron diffraction experiments were performed exemplarily for 1‐(pentafluorophenoxy)‐2‐(phenoxy)ethane. A new procedure for structure refinement was developed to deal with the conformational complexity of such molecules. The results are an experimental confirmation of the existence of folded conformations of this molecule with short intramolecular
