Abstract <p>The study is aimed at describing the processes of transport in polar media within the molecular kinetic theory. In the course of the study, the potential of interaction of molecules has been built, which is a superposition of the model developed by the authors previously and the Stockmayer potential. Based on the introduced potential for polar media, the method of contraction operators has been substantiated and adapted to search for the point of the maximum approach of molecules. In addition, test calculations have been performed to search for coordinates of the point of the maximum approach of molecules for a polar medium—water. In the future, the results will be used in computational technologies for determining the transport characteristics of polar media within the kinetic theory of gases, i.e., the Boltzmann equation.</p>
