The 1 H NMR spectra of phthalide in Merck Nematic Phase IV and in N ‐( p ‐ethoxybenzylidene)‐ p ‐ n ‐butylaniline (EBBA) and of 2‐coumaranone in Merck Nematic Phase IV were analyzed. Structural parameters were obtained. The planarity of the 5‐membered ring and the molecular orientations were discussed.
