M06-HF: Global hybrid functional with 100% HF exchange. Intended for charge transfer TD-DFT and systems where self-interaction is pathological. The M06 and M06-2X functionals introduce 35 and 32 empirically optimized parameters, respectively, into the

M06-L is fully local without HF exchange (thus it cannot be considered hybrid), M06 has 27% HF exchange, M06-2X 54% and M06-HF 100%. The advantages and usefulness of each functional are M06-L: Fast, good for transition metals, inorganic and M06: For

We present a comparative assessment of the performance of the M06 suite of density functionals (M06, M06-2X, and M06-HF) against an MP2 benchmark for calculating the relative energies and geometric structures of the Cl–·arginine and Br–·arginine halide ion

The M06 suite of functionals are a set of four meta-hybrid GGA DFT functionals. They are constructed with empirical fitting of their parameters, but constraining to the uniform electron gas. The family includes the functionals M06-L, M06, M06-2X and M06-HF, with a

The revM06 functional also predicts more accurate results than M06 and M06-2X for most of the outside-the-training-set test sets examined in this study. Therefore, the revM06 functional is well-suited for a broad range of chemical applications for both main-group

Our information about functionals is organized both by program and by functional. This page contains the density functionals developed in the Truhlar group on the second, third, and fourth rungs of the ladder of functionals; our fifth-rung functionals (that is

In the Kohn-Sham formulation of density functional theory [], the exact exchange (HF) for a single determinant is replaced by a more general expression, the exchange-correlation functional, which can include terms accounting for both the exchange and the electron

8/8/2017 · Here we present a revised M06-L functional, named revM06-L, which gives both smoother potential energy curves and improved overall accuracy, especially for chemical reaction barrier heights, noncovalent interactions, and solid-state physics.

How to include M06-2X in Gaussian 09 Revision A? It is not included in the theoretical model list. How to add this model? (4 functional groups I am interested in and 8, 10, 12, 14, 16) water molecules neighbouring) only three of the twenty ran successfully

We investigated the performance of the density functional theory (DFT) functionals PBE, PBE0, M06, and M06‐L for describing the molecular and dissociative adsorption of O 2 onto pure and doped Al(111) surfaces. Adsorption of O 2 was studied at the perfect Al

I want to use M06-2X DFT functional in conjunction with 6-31G* basis sets in cp2k version 6.1.0. In this purpose I used libxc library, where, only XC_MGGA_C_M06_2X functional is supported in cp2k version 6.1.0 and the XC_MGGA_X_M06_2X and

I am trying M06-L/ 6-31+G (d,p) and M06-L/LANL2DZ with keywords “auto integral=ultrafine”, but I am unable to calculate. Any ideas what should I put on the input file to use this functional correctly

It comes with somewhat built in non-covalent interactions and other features. This functional (like most other though) will fail horribly, if you have multi-reference character in your system. The M06-HF functional incorporates 100% Hartree-Fock exchange and was

The hybrid functional M06 has smaller X than M062X (27 vs. 54). In CAM-B3LYP, X is not a constant and increases from 19 to 65 as interelectronic separation increases. Only CAM-B3LYP predicts the same absorption energy combines the advantages of M06

The M06-L density functional has been assessed for its ability to predict the correct structure of a Tyr–Gly conformer for which MP2/6-31+G(d) predicts a folded ‘closed book’ conformer, whereas a more open conformation is predicted by B3LYP/6-31+G(d).
