Abstract
We use the maximum entropy internal order (MEIO) method to reanalyze p ublished (1)HNMR dipolar couplings for biphenyl dissolved in nematic s olvents allowing for geometry variations with dihedral angle phi. We f ind that all present experimental data are consistent with similar con formational distributions with a maximum at phi = 34 - 35 degrees. Lit tle rotational-conformational coupling has been found.
