Abstract : Part I of the report is an extension of Eyring's Significant Structure Theory of the liquid state to high pressures. This extension is accomplished by introducing a Lennard-Jones and Devonshire cell model for calculating the energy of cold compression used in the solid part of the partition function. This potential is used to determine the frequency of oscillation in an Einstein solid or to determine the total classical partition function. Part II examines the basic physical concepts of the liquid state and proposes an alternative to the Eyring hole theory based on the mobility of atoms trapped between two partially separated layers. Some predictions based on this model are compared with experimental data. (Author)
