Quantum theory of atoms in molecules for photovoltaics

Solar Energy, 2019
Abstract Electronic properties of benzothiadiazole (BTD) unit containing dyes adsorbed on TiO2 nano-particles have been estimated using Quantum Theory of Atoms in Molecules (QTAIM). We found that short circuit photocurrent density Jsc and open circuit photovoltage Voc of the studied DSSCs are well related to the electronic properties of dyes, namely ...

The kernel energy method applied to quantum theory of atoms in molecules – energies of interacting quantum atoms

Chemical Physics Letters, 2019
Abstract The Kernel Energy Method (KEM) has been widely applied to predict the properties of large molecules from kernels fragments in a fast and reliable manner. Kernels are typically made of many atoms raising the question: Is the accuracy of KEM traceable to the atomic level? An exact atomic decomposition of the molecular energy within the Quantum

Inductive Effect: A Quantum Theory of Atoms in Molecules Perspective

The Journal of Physical Chemistry A, 2011
Substituent effects are ubiquitous in chemistry and the most fundamental is the inductive effect. In this study, the so-called inductive effect was probed in derivatives of bicyclo[1.1.1]pentane-1-carboxylic acid using the isodesmic reaction energy of the acid-base deprotonation, calculated at the PBE0/6-31++G(d,p) level of theory (used throughout ...

Two-electron integrations in the quantum theory of atoms in molecules

The Journal of Chemical Physics, 2004
A method to compute two-electron integrals over arbitrary regions of space is introduced and particularized to the basins appearing in the quantum theory of atoms in molecules. The procedure generalizes the conventional multipolar approach to account for overlapping densities. We show that the approach is always convergent and computationally efficient,
