Behavior of anisotropic and isotropic intermolecular interactions in liquids

An approach to evaluating the effect of temperature on the parameter determining the energy of intermolecular interactions (IMI) in liquids was developed. Within the framework of this approach, with consideration given tothe energy of IMI in saturated vapors, this effect was examined over the temperature range from the melting point to the critical temperature for 12 polar and nonpolar associated and nonassociated individual liquids, as an example. The properties of the anisotropic and isotropic components of internal energy of IMI were calculated and analyzed for about 190 liquids mostly at 20°C. The conclusion that the isotropic component ΔU i s of the internal energy of IMI is an additive quantity was confirmed for most of the liquids under study. The component At/is was found to depend not only on the composition but also on the structure of the molecule. The effect of intermolecular hydrogen bonding in protic liquids on the anisotropic At/an and isotropic components of the internal energy of intermolecular interactions was examined. Polar liquids (prussic acid and monoalkyl derivatives of formamide and acetamide) with anomalously high At/an values and positive ΔU i s were identified and analyzed for the first time.
