Spin–spin coupling between all three nuclei of a hydrogen bridge is seen for the first time. The observation of these couplings in the hydrogen fluoride/collidine complex (see figure) reveals a covalent character of the hydrogen bridge. Its geometry is strongly affected by temperature dependent solvent electric field effects.
