This energy also includes anharmonicity, bonded and nonbonded energy in accordance to the Hookian principle. The different atom types that contribute to the bond energies and thermal properties were calculated in MM2 using the Buckingham equation for van der Waal interaction instead of Lennard-Jones [20]. Chemical properties for drug likeliness of the compounds like molecular weight, number of rotatable bonds, hydrogen bond acceptor and donor were predicted using MolSoft (Molsoft LLC. ICM Browser 3.7).
