## Abstract The ^1^H and ^13^C NMR spectra of __s__‐trioxane partially oriented in three nematic solvents were analysed, and the measured dipolar coupling constants, corrected for harmonic vibrations and for correlated deformation, were used to obtain information about the __r__~α~ structure of the

✦ Synopsis
Abstract
The indirect and direct proton–proton, proton–carbon and proton–nitrogen coupling constants of benzonitrile have been measured from proton spectra with natural abundance satellites, and also from proton and ^15^N spectra of the molecule enriched in ^13^C or ^15^N at the cyano group, both in isotropic as well as in oriented solvents. The r~α~ structure of the entire molecule has subsequently been determined.

## Abstract The convolution molecule method by Hoppe and Paulus yields sometimes several solutions for the orientation of the molecule. For the selection of the correct orientation a special kind of __R__ value (mean __R__ value) can give valuable information.
