4.2 Density functional theory methods Computational chemistry is a branch of chemistry that uses computer simulation to assist in solving complex chemical problems. It exploits methods of theoretical chemistry, incorporated into efficient computer programs, to calculate the structures, the interactions, and...
More Gaussian 16 offers a wide variety of Density Functional Theory (DFT) [Hohenberg64,Kohn65,Parr89,Salahub89] models (see also [Labanowski91,Andzelm92,Becke92,Gill92,Perdew92,Scuseria92,Becke92a,Perdew92a,Perdew93a,Sosa93a,Stephens94,Stephens94a,Ricca95] for discussions of DFT methods and ...
A variety of density functional theory (DFT) methods are paired with Pople basis sets of varying sizes and evaluated for use with organoselenium compounds. The ability of each method to predict reliable geometries and energies is determined through comparison with quadratic configuration interaction with...
