Molecular mechanics calculations were employed to study the inclusion of 2-methyl naphthoate in α- and β-cyclodextrinin vacuoand in the presence of water as a solvent. The driving forces for complexation are dominated by nonbonded van der Waals host:guest inteMolecular mechanics calculations were employed to study the inclusion of 2-methyl naphthoate in α- and β-cyclodextrinin vacuoand in the presence of water as a solvent. The driving forces for complexation are dominated by nonbonded van der Waals host:guest interactions in both environments. The 2-methyl naphthoate penetrates completely into the cavity of β-cyclodextrin, but there is only partial penetration by the same molecule into the smaller cavity of α-cyclodextrin.[+][-]
