The NMR spectrum of pyrimidine has been studied in the nematic phase of 4‐methoxy benzylidene‐4‐amino‐α‐methyl cinnamic acid‐ n ‐propyl ester at room temperature. The ratios of all the interproton distances are determined and found to differ significantly from those obtained from microwave data. The molecule, like other aromatics, is shown to orient preferentially with its plane in the direction of the magnetic field.
