Abstract
The structure factor S m (Q) of liquid benzene and naphthalene have been measured by means of pulsed neutron total scattering. Both intramolecular and intermolecular structures are discussed. The intermolecular structures are analyzed by taking account of orientational correlations introduced between the nearest neighbors and a packing of uncorrelated molecules. The experimental S m (Q) and the radial distribution function of liquid benzene are reproduced reasonably well by introducing a perpendicular orientation just between the nearest neighbors. The analysis of liquid naphthalene suggests an orientation somewhat similar to that in liquid benzene.Keywords
