The rα structure of C6F5Br determined by 13C NMR in liquid crystal. Distortions of the C6F6 ring induced by single substitution

Fluorine-carbone-13 dipolar couplings are more advantageously extracted from C-13 NMR spectrum of C6F5Br (figure above) than from the F-19 with C13-satellites one. Corrected for vibrations, these couplings lead to the structure of this molecule.
