Quantum topology of the charge density of chemical bonds. QTAIM analysis of the C-Br and O-Br bonds

Abstract

The present study aims to explore the quantum topological features of the electron density and its Laplacian of the understudied molecular bromine species involved in ozone depletion events. The characteristics of the C-Br and O-Br bonds have been analyzed via quantum theory of atoms in molecules (QTAIM) analysis using the wave functions computed at the B3LYP/aug-cc-PVTZ level of theory. Quantum topology analysis reveal that the C-Br and O-Br bonds show depletion of charge density indicating the increased ionic character of these bonds. Contour plots and relief maps have been analyzed for regions of valence shell charge concentrations (VSCC) and depletions (VSCD) in the ground state.
