A statistical-mechanical theory based upon the method of conditional distri
bution function has been applied to calculations of the nearest-neighbor (N
N) and next NN correlators as well as order parameters. The method takes in
to account translational and orientational correlations as well as their co
upling. Using the dipolar Gay-Beme interaction potential, calculations have
been carried out for temperatures and densities corresponding to a nematic
phase. The results in orientational distribution functions indicate a sign
ificant effect of the dipole-dipole interactions on the orientational order
of the liquid crystal. It was found that NN particles tend to be mutually
antiparallel, whereas a reversed tendency is observed for next NN particles
. These results are in agreement with computer simulations and with interpr
etations of experimental data. [S1063-651X(99)50508-4].
