J Chem Theory Comput. 2014 Jun 10;10(6):2479-87. doi: 10.1021/ct500291x. Epub 2014 May 22.

The effect of anharmonic corrections to the vibrational energies of extended systems is explored. Particular attention is paid to the thermodynamics of adsorption of small molecules on catalytically relevant systems typically affected by anharmonicity. The implemented scheme obtains one-dimensional...
