Proton Magnetic Resonance in Liquid Crystals—Orientation Effects

This communication reports a study of the proton magnetic resonance signal from the liquid crystal phase of 4‐4′ methoxyazoxybenzene, 4‐4′ methoxy D3 azoxybenzene, and 4‐4′ ethyoxyazoxybenzene in an effort to obtain information concerning the temperature dependence and relative extent of the molecular orientation in such phases. The experimental results lead to a qualitative picture of the distribution of molecular orientations for the first two compounds and show that the extent of orientation in the last compound is greater than in the first two.
