The ' H and '% NMR spectra of 15 modified representatives of Troger's base were recorded and the corresponding signals assigned. In 'H NMR, the appearance of the AABB'CC'(XX) system, after irradiation of H,(H,), is deceptively simple and should not be first-order analysed. The 13C chemical shifts an
