In this work, we propose a simple approach for the deteror dispersive component of the surface free energy and surface mination of the London dispersive component of the surface enthalpy of a solid, starting with the knowledge of the adsorption free energy using nonpolar probes such as n-alkanes in IGC, behavior of a -CH 2 -group of linear long-chain hydrocarbons.
