Virial theorem and the two molecule interaction potential
Annotation
A method for determining the parameters of the two-molecule interaction potential is shown by the example of the Mie potential or the four-parameter Lennard–Jones potential (GLJ). The application of the virial theorem with respect to the Mie potential allows one to determine exponents at the intermolecular distance. The application of the theory of pair collisions for determination of the intermolecular repulsion potential is shown by the example of a number of substances. The statistic characteristic of gases that allows one to formulate the intermolecular attraction potential is found.
