Liquid Structure of Carbon Tetrachloride and Long-range Correlation

Abstract
The diffraction of liquid CCl4 was measured by using the energy-dispersive X-ray diffractometer. The fine structure was observed for the first time in the present study. The existence of the fine structure in the diffraction pattern shows the long-range correlation “directly.” The bcc cluster model for liquid CCl4 is presented on the basis of the long-range correlation. The calculated intensity of the model is in good agreement with the observed one.
