The main objective of this study was to consider the problem of whether or not information about intermolecular interactions can be obtained from the examination of macroscopic properties of various systems. In this study it was chosen to investigate the intermolecular interactions of a liquid-liquid system. The liquid-liquid system, dioxane-water, was selected for two reasons. First, a considerable amount of work has been done on this particular systems so there is a large body of information with which to work and with which correlations can be made. Secondly, there is a large discrepancy among the interpretations of the results of experimental work done on the system, especially as to the molecular “complexes” formed between dioxane and water. There have been a number of studies performed where considerable disagreement on interpretation of results occurs for measurement of the very same quantities. The experimental work discussed in this paper consists mainly of a more extensive examination of the surface tension property than has previously been done, as well as an infrared study of the dioxane-water system. Finally, it was shown that there is a good possibility of strong interaction between dioxane molecules, an idea previously rejected because of the apparent inability of the dioxane hydrogen atoms to participate in dipole type interactions.
