STUDY OF RELATION BETWEEN PITZER’S ACCENTRICITY AND INERTIA OF ROTATIONAL MOTION
The article presents the results of studies of the relationship between the eccentricity of ε molecules as ellipsoids of revolution and the acentricity of ω molecules according to Pitzer. Pitzer acentricity is determined from data on critical boiling points, critical volumes, and critical pressures. It is shown that there is no dependence between these factors, therefore, it is proposed to use the ratio of the moments of inertia of the rotational motion of molecules along two axes as a structural descriptor in the description of acentricity. The obtained data are compared with data published by other authors.
