Comments on Second caloric virial coefficients for real gases and combined spherical symmetric potential for simple molecular interactions

TL;DR

This paper critically evaluates proposed interaction potentials for various gases and finds they fail to accurately predict experimental second virial coefficients across a broad temperature range.

Contribution

It provides a detailed analysis showing that existing potentials do not match experimental data, highlighting the need for improved models.

Findings

Existing potentials do not fit experimental data within uncertainties.

Most models fail across a wide temperature range.

Highlights the necessity for more accurate interaction potentials.

Abstract

It is shown that the interaction potentials for argon, krypton, xenon, carbon dioxide, ammonia, water, n-pentane, n-octane, 1-propanol, suggested in [1] cannot describe experimental second density virial coefficient data within their uncertainty over a wide temperature range.
