N.M.R. spectra of pyrazine and p-benzoquinone oriented in a nematic phase

Abstract
N.M.R. spectra of pyrazine and p-benzoquinone have been studied in the nematic phase of p,p′-di-n-hexyloxyazoxybenzene. Information about the geometry of these molecules has been obtained. The angle between the CH and the CC bonds has been determined. The chemical shift anisotropy in both the molecules is reported.
