The proton and fluorine magnetic resonance spectra of ortho-, meta-, and para-difluorobenzene dissolved in a nematic liquid crystal solvent have been analyzed. Expressions for the anisotropy of the fluorine chemical shift were obtained but an attempt to fit these to the Karplus and Das theory failed. Hydrogen atoms ortho to fluorine show small displacements from their expected positions.
