Equivalence in anisotropic N.M.R. spectra: the spectrum of ethyl iodide in the nematic phase

It is shown how the composite particle technique, which has proved useful for the analysis of the spectra of molecules in the isotropic liquid phase, may also be applied, with slight modifications, to spectra observed in an anisotropic environment. As an example, the analysis of the spectrum of ethyl iodide in the nematic phase is described.
