Abstract
N.M.R. spectra of ortho dibromo, dichloro and dicyano benzenes have been studied in liquid crystalline nematic phases. The spectra have been analysed iteratively. The direct couplings are found to be of opposite sign compared to the indirect ones. Ratios of the various inter-proton distances in these molecules are determined. They do not deviate significantly from the corresponding ratios in unsubstituted benzene.Keywords
