Modern dispersion-corrected DFT methods yield more accurate molecular geometries
the verdict
SUPPORTED
the evidence backs this
confidence 58/100
Modern dispersion-corrected density functional theory (DFT) methods generally yield high accuracy for molecular geometries and noncovalent interactions, as supported by multiple benchmark and structural studies, though exceptions exist for certain intramolecular conformational energies.
