Density overlap regions indicator
WebCorminboeuf developed the Density Overlap Regions Indicator (DORI), which allows the prediction of bonding and non-covalent interactions between molecular systems. She has made use of machine learning to understand the material properties of large systems that consist of non-covalent interactions, such as Van der Waals forces , halogen bonds ... WebJan 12, 2024 · The Quantum Theory of Atoms in Molecules (QTAIM) and Density Overlap Regions Indicator (DORI) approaches were used to obtain an in-depth characterization of the intramolecular hydrogen bridge in the studied compounds. For this purpose, four snapshots of the CPMD trajectory in the gas phase for each compound and each …

WebMay 1, 2016 · The recently introduced density overlap regions indicator (DORI) is another scalar field, which like NCI is derived from the ED and its derivatives: Θ(r) = ( ( ρ(r)/ρ(r)) 2) 2 /( ρ(r)/ρ(r)) 6. Since Θ(r) becomes infinite at bonding regions a transformation γ(r) = Θ(r)/(1 + Θ(r)) is applied to obtain values between zero and one. It does ... WebIn this thesis, original applications of the Density Overlap Region Indicator (DORI), a density dependent bonding descriptor capable of simultaneously capturing covalent and noncovalent interactions, are discussed. The use of scalar fields, such as DORI, were …

WebThe accuracy and efficiency of a density functional is dependent on the basic in-gredients it uses, and how the ingredients are built into the functional as a whole. An iso-orbital indicator based on the electron density, its gradients, and the kinetic energy density, has proven an essential dimensionless variable that allows density functionals
WebIn this work, we propose a new real space function named interaction region indicator (IRI), which is a slight modification on RDG. We found IRI can reveal chemical bonding and weak interaction regions equally well, which brings great convenience in the study of various chemical systems as well as chemical reactions. ...
