Description
Summary:The x-ray diffraction and the depolarization ratio of the ν1 Raman line were measured in liquid carbon tetrachloride. The previously proposed liquid structure models for an x-ray diffraction pattern were found to be difficult to distinguish from each other. It has been reported that the relation between the local structure and its fluctuation corresponds to the depolarization ratio of the ν1 Raman line in liquid carbon tetrachloride [S. Hyodo and T. Fujiyama, Bull. Chem. Soc. Jpn. 53, 2456 (1980)]. The information obtained from this correspondence suggests that those models were clearly distinguishable. The contribution of the fluctuations of the molecular center and molecular orientation and that of the distortion from the temporarily assumed ideal lattice structure were also discussed to both the x-ray diffraction curve and the depolarization ratio.
