Neutron diffraction study of liquid benzene
This paper describes a neutron diffraction study of liquid benzene. The experiment described herein was made by the Time-of-Flight method using an electron linear accelerator. The molecular structure factor S/sub m/(Q) with the wide range of Q at about 1 - 30 A/sup -1/ was obtained from the measurements at the scattering angles of 45/sup 0/ and 150/sup 0/. The dynamical effect, which causes problems in neutron diffraction experiments of light nuclei liquids, was successfully corrected. In this study the parameters for the intramolecular structure were derived from S/sub m/ (Q) in the high Q region. Furthermore, a simple model calculation method, which can effectively include the coupling effect between the spatial and the orientational correlations, was proposed for the intermolecular structure of nonspherical molecular liquids. The calculation done on the model with three types of arrangements for the two benzene molecules can explain well the characteristic structure in the low Q region of liquid benzene.
