Computational studies of molecular hydrogen binding affinities: The role of dispersion forces, electrostatics, and orbital interactions
Rohini C. Lochan and Martin Head-Gordon
Intermolecular interactions between H2 and ligands, metals, and metal–ligand complexes determine the binding affinities of potential hydrogen storage materials (HSM), and thus their extent of potential for practical use. A brief survey of current activity on HSM is given. The key issue of binding strengths is examined from a basic perspective by surveying the distinct classes of interactions (dispersion, electrostatics, orbital interactions) in first a general way, and then in the context of calculated binding affinities for a range of model systems.
