The atomic structure of pentacene. Density-Functional Theory (DFT) is one of the most prominent ab initio quantum chemistry tools available to provide insight about atoms, molecules, biomolecules, and beyond. Metal complexes are becoming increasingly important as the photochemical building blocks of functional molecular systems such as sensors and photoelectrochemical cells. Monograph and Report Series, Number Three. Researchers use atomic force microscopy to image the chemical structure of the small molecule pentacene, with atomic resolution.

But they also performed density functional theory calculations, which confirmed that the pentacene images were what they should have seen. Of particular interest are metal complexes that involve gold atoms in the +1 valence state, due to their ability to self-assemble into 1)—an interpretation backed by DFT computations correlating the oscillation frequencies to gold–gold stretching vibrations. Density-functional theory calculations have been used to investigate adsorption and surface dynamics of Pt atoms on MgO(001) surfaces with surface-functional hydroxyl groups.

Excited states can be computed within the Time-Dependent Density Functional Theory (for molecules), or within Many-Body Perturbation Theory (the GW approximation).
