Significance of the Tolman length at a molecular level

It is shown that, by assuming valid a relationship between the work of cavity creation in a liquid and the bulk liquid–vapour surface tension, corrected for curvature effects, and by reproducing calculated ΔGc values to create in water and n-hexane a cavity suitable to host a methane molecule, the obtained estimates of the Tolman length prove to markedly depend on temperature, losing a precise physical meaning.
