Molecular alignment of binary mixtures, induced by an external electric field, has been studied as a function of mixture composition. The alignment factors were calculated from the quadrupolar splittings in the 2H-NMR spectra. The investigated mixtures were: nitrobenzene/ethylenecarbonate, nitrobenzene/acetonitrile and acetonitrile/benzene. Intermolecular interactions strongly affect alignment. The results are discussed in terms of geometry changes and/or changes in the asymmetry parameters of 2H quadrupole coupling constants.
