## Abstract Linear relationships between the inverse of the quadrupolar coupling constant, 1/χ and the asymmetry parameter η are obtained for the ^7^O‐nucleus of acetone oriented in four different nematic phases, using the information contained in ^1^H‐ and ^17^O‐NMR spectra. The absence of a uniqu

✦ Synopsis
Two bond spin-spin coupling constants 2J(170iH) are determined for the oxygen in ether, aldehyde, acid, ester and amide groups by line shape analysis of the corresponding I7O NMR spectra.

## Abstract The preferred conformations of the methylsulphinyl group in a number of phenyl methyl sulphoxides substituted in the phenyl ring with one, two or three fluorine atoms have been studied by employing a multinuclear NMR approach. From the ^1^H, ^13^C and ^17^O chemical shifts of the methyl
