Abstract

The proton spectrum with ^13^C satellites of benzaldehyde oriented in a liquid crystal solvent has been analysed and the structure of the proton and carbon skeleton has been determined. The large number of observed direct couplings also allows the study of the intramolecular rotation. The depth of the hindering potential is extremely model dependent, however, so that no unique result has been obtained.
