Previous
attempts to analyze the proton spectrum of ethylbenzene as a solute in nematic liquid crystalline solvents
failed, but a successful strategy has now been devised and is described here. The proton spectra of samples
of ethylbenzene dissolved in four different liquid crystals have been analyzed to yield sets of the partially-averaged
dipolar couplings, Dij. The couplings
are then used to test
models for the structure and conformation of this molecule.

The 3Δ‐deuteriumisotopeeffects of partially and fully deuteriated tert‐butyl groups on the 13C NMRspectra of tert‐butylbenzene and derivatives are discussed in detail. It is shown that they correlate with the chemical shift of C‐1 of the aromatic ring. It has been demonstrated that when deuterium is replaced with some other substituents, the SCS values of these substituents show a parallel behaviour
