The p.m.r. spectra of 1,4-dichlorobenzene-(13C and 12C) partially oriented in nematic phases have been measured and analyzed, and the geometry of the molecule has been determined. The angle [Formula: see text] is found to be 119.4° and [Formula: see text] 120.3°. The JCH are determined using spectra of samples with differing degrees of orientation.

Proton magnetic resonance spectra of 1,4-dibromobenzene (13C and 12C) partially oriented in nematic phases have been measured and analyzed, and the geometry of the molecule has been determined. The angle [Formula: see text] is found to be 120.02 ± 0.01° and the angle [Formula: see text]with the assumption that all CC bond distances are of equal length the angle [Formula: see text] The JCH are determined using three spectra of samples with differing degrees of orientation.
