The 1H and 13C nmr spectra of three cyclic sulphonium salts ol dithiacyclophanes have been recorded and compared with those of the open-chain analogue. The 1H spectra indicate that methylation of the dithiacyclophanes gives a mixture of eonformationa

The interpretation of the 1H n.m.r. spectrum of a meta-substituted biphenyl (3,3′,5,5′-tetrachlorobiphenyl) dissolved in the nematic phase of a liquid crystalline solvent showed unambiguously that in solution it has neither a planar structure nor

The 13C n.m.r. spectra of the four symmetrical naphthyridines have been obtained and assignment of the signals performed by means of heteronuclear decoupling experiments and empirical additivity methods. The shifts were found to depend linearly upon
