Abstract: An analysis of the change in the Gibbs free energy $\Delta G$ upon the formation of a flat nucleus of a $p$-terphenyl crystal at the liquid – air interface is presented, taking into account the anisotropy of the surface energy of the faces. The surface energy values of the $p$-terphenyl crystal faces were calculated by the atomic force field method OPLS, based on structural data. Experimental information on crystal growth from solutions and their surface properties was used to analyze the model.

Keywords: nucleation of crystals, surface energy, surface tension, liquid-air interface, wetting, free Gibbs energy.
