چکیده

Following the work on spin-component and spin-opposite scaled (SCS/SOS) global double hybrids for singlet-singlet excitations by Schwabe Goerigk [ J. Chem. Theory Comput. 2017, 13, 4307-4323] our own works new long-range corrected (LC) singlet-triplet 2019, 15, 4735-4744 Phys. 2020, 153, 064106], we present LC with SCS/SOS that demonstrate further improvement over previously published results methods. We introduce unscaled versions of different based Becke88 or PBE exchange combined LYP, PBE, P86 correlation. For excitations, cross-validate them six benchmark sets cover small to medium-sized chromophores excitation types (local-valence, Rydberg, charge transfer). perform cross-validation three following same analysis as in previous 2020. In total, 203 are analyzed. Our confirm extend those regarding superior performance SCS SOS variants compared their parents decreasing mean absolute deviations, root-mean-square error spans more than half bringing deviations closer zero. shown be highly efficient robust computation vertical energies, which even outperform specialized also contain an perturbative part. particular, SCS/SOS-?PBEPP86 SCS/SOS-?B88PP86 functionals four most accurate methods tested this work, fully recommend future applications. However, if relevant algorithms not available user, suggest ?PBEPP86 best method work.

Long-range corrected double-hybrid density functionals.

We extend the range of applicability of our previous long-range corrected (LC) hybrid functional, omegaB97X [J.-D. Chai and M. Head-Gordon, J. Chem. Phys. 128, 084106 (2008)], with a nonlocal description of electron correlation, inspired by second-order Moller-Plesset (many-body) perturbation theory. This LC "double-hybrid" density functional, denoted as omegaB97X-2, is fully optimized both at ...

Long-Range Corrected Hybrid Density Functionals with Improved Dispersion Corrections.

By incorporating the improved empirical atom-atom dispersion corrections from DFT-D3 [Grimme, S.; Antony, J.; Ehrlich, S.; Krieg, H. J. Chem. Phys.2010, 132, 154104], two long-range corrected (LC) hybrid density functionals are proposed. Our resulting LC hybrid functionals, ωM06-D3 and ωB97X-D3, are shown to be accurate for a very wide range of applications, such as thermochemistry, kinetics, n...

Systematic optimization of long-range corrected hybrid density functionals.

A general scheme for systematically modeling long-range corrected (LC) hybrid density functionals is proposed. Our resulting two LC hybrid functionals are shown to be accurate in thermochemistry, kinetics, and noncovalent interactions, when compared with common hybrid density functionals. The qualitative failures of the commonly used hybrid density functionals in some "difficult problems," such...

Computation of accurate excitation energies for large organic molecules with double-hybrid density functionals.

Time-dependent double-hybrid density functional methods are evaluated for the calculation of vertical singlet-singlet valence excitation energies of a wide variety of organic molecules. Beside the already published TD-B2-PLYP method, an analogous approach based on the recently published ground state B2GP-PLYP functional is presented for the first time. Double-hybrid functionals contain a hybrid...

Long-range corrected hybrid density functionals with damped atom-atom dispersion corrections.

We report re-optimization of a recently proposed long-range corrected (LC) hybrid density functional [J.-D. Chai and M. Head-Gordon, J. Chem. Phys., 2008, 128, 084106] to include empirical atom-atom dispersion corrections. The resulting functional, omegaB97X-D yields satisfactory accuracy for thermochemistry, kinetics, and non-covalent interactions. Tests show that for non-covalent systems, ome...
