Empirically corrected DFT and semi-empirical methods for non-bonding interactions
文献信息

Computational modeling of systems governed by non-bonded interactions, especially van der Waals (dispersion) interactions, is currently a difficult task, since many conventional quantum mechanical techniques neglect such interactions. For example, the popular semi-empirical and Hartree–Fock methods, as well as most DFT methods all neglect long-range dispersion. In attempt to model dispersion interactions at reduced computational expense, one approach is to add an empirical potential to one of the quantum mechanical techniques. This approach has been successfully used to model a large variety of systems that involve, or are governed by, dispersion interactions. The accuracy of empirically-corrected density functional theory (DFT-D) and empirically-corrected semiempirical (SE-D) methods are reviewed here. The analysis considers both the ability to reproduce benchmark energies and geometries.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
