BLYP functional - Big Chemical Encyclopedia

Hybrid functionals are a class of approximations to the exchange–correlation energy functional in density functional theory (DFT) that incorporate a portion of exact exchange from Hartree–Fock theory with the rest of the exchange–correlation energy from other sources (ab initio or empirical). The exact exchange energy functional is expressed in terms of the Kohn–Sham orbitals rather than the density, so is termed an implicit density functional. One of the most commonly used version… WebThe uncorrected B3LYP functional, shown at the bottom line of Table 1, performs badly, with a very shallow minimum (small D and large R 0) under 6-31+G* basis and no minimum for def2TZVP, i.e., demanding an anti-Morse fit. The middle lines of Table 1 suggest that GGA functionals performed badly. BLYP yields non-bonded (anti-Morse) curves for ... diabetic muscle aches after tennis
