Abstract

The 80 MHz 1H NMR and 20 MHz 13C NMR spectra of eleven substited benzalazines (subsituenst: α‐methyl, α,α′‐dimethyl, 2‐hydroxy, 2,2′‐dihydroxy, 4‐n‐octyloxy, 4,4′‐di‐n‐octyloxy) possessing mesogenic acivity have been assigned using a variety of one‐dimensional techniques. These include homonuclear NOE measurements, selective heteronuclear 13C{1H} NOE difference spectroscopy, singlefrequency off‐resonance decoupling, spin—echo multiplicity sorting (SEFT) and long‐range heteronuclear coupling constant determintion via both gated decoupling and selective excitation (DANTE).
