To achieve such studies, efficient density functional theory DFT formalisms, based on various levels of approximate computational schemes, have been developed, and provide a good alternative to commonly used DFT implementations.

Density-functional based tight-binding DFTB is an efficient quantum mechanical method that can describe a variety of systems, going from organic and inorganic compounds to metallic and hybrid materials. A, — The successive hydrogenation of CO is supposed to be the main mechanism leading to the formation of complex oxygenated species in the interstellar medium, possibly mediated by ice layers or ice grains.

Citons les deux principaux contributeurs: Metadynamics combined with auxiliary density functional and density functional tight-binding methods: Since my two-years post-doc in the group of Pr. The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, revealing that the formation of hydrogen bond interactions with protic solvents is responsible for a dramatic enhancement of the fluorescence quantum yield in the far-red spectral region.
