Rpbe functional
Webconstructed by optimizing one parameter of the PBE functional against the exchange energy of noble gas atoms from He to Ar.7 It improves the atomization energies and chemisorption energies over the PBE functional. The RPBE functional8 gives nearly the same chemisorption energies as the revPBE function, without any fitting of parameters. WebWhereas the dispersion-corrected RPBE functional yields a good description of both the water–water and the water–metal interaction, the dispersion-corrected PBE functional overestimates the energies of both systems. In contrast thereto, the adsorption distances predicted by the PBE functional is hardly changed due to the additional ...
