Density functional theory calculations have become ubiquitous in every area of chemistry. This tutorial review focuses on different issues that arise from the choice of the method or from technical details that are too often overlooked. It is mainly intended for nonexperts in the field or for ...
In this tutorial review, we show how Time-Dependent Density Functional Theory (TD-DFT) has become a popular tool for computing the signatures of electronically excited states, and ... 查看全部>>doi:10.1039/c2cs35394fCarlo AdamoDenis Jacquemin...

Kohn-Sham density functional theory (DFT) is a standard tool in most branches of chemistry, but accuracies for many molecules are limited to 2-3 kcal⋅mol−1with presently-available functionals. Ab initio methods, such as coupled-cluster, routinely produce much higher accuracy, but computatio...

Density Functional Theory (DFT) computes the energy of a many-electron atom or molecule as a functional of the one-electron densityρ rather than the many-electron wavefunctionψ(r1,r2, ...,rN). • Formally, DFT relies upon the Hohenberg-Kohn theorem (1964) which states that the ...
