ResumoNuclear magnetic resonance spectra of 1,3-difluorobenzene in thermotropic and lyotropic nematic solvents have been measured and interpreted. The geometrical data calculated from the dipolar couplings are compared with those obtained from microwave spectra and from a recent electron diffraction experiment. Evidence has been found of a small anisotropy in the indirect fluorine-fluorine coupling.
