Abstract A technique to obtain infrared absorption spectra of orientated molecules, dissolved in a liquid crystal, which is placed in a strong magnetic field, is described. The degree of orienta­tion of 4,4'-dihexoxyazoxybenzene is measured at various temperatures. The maximum degree of orientation of 4-bromo-benzonitrile and 4-cyanobenzoic acid is measured in a 10% solution in 4,4'-dihexoxyazoxybenzene to be 0.35 and 0.55, respectively.
