Hint:Remember that sigma bonds are characterized by head-on overlaps, which can occur between different types of orbitals. Step 2: Identify Types of Overlaps There are three main types of overlaps that can lead to the formation of sigma bonds: 1.S-S Overlap: This occurs when two s orbitals...
The characteristics of ci expansions based on different types of orbitals (all obtained from the same basis set) are compared in a series of calculations on the water molecule. The orbitals compared include canonical SCF molecular orbitals, natural orbitals, and two other types related to these. ...
The calculations were performed using the pseudopotential DFT package SIESTA36,37, which uses numerical atomic orbitals as the basis set, allowing for very efficient, but still reliable calculations. We used the local density approximation (LDA) exchange correlation potential, with Ceperley-Alder parame...
The quantum orbitals entitled as HOMO and LUMO unveil charge transfer efficiency from the higher to lower levels in a molecule37. The HOMO is known as the electron donor orbital while, the LUMO is at a lower energy level, regarded as the electron acceptor molecular orbital38. The FMO energy...
One example of the pyramidalization angle belonging to C60 fullerene is 11.6o [3, 4], which means that a 101.6o angle was formed between the σ and π orbitals in a carbon atom. Among various types of fullerene, the most commonly known and most stable species is Buckminsterfullerene, or ...
An equally important goal has been the comparison and discussion of the photo- and redox reactivity of these complexes from the viewpoint of the frontier orbitals involved and character of the Ru X/X′ bonding.doi:10.1016/S0010-8545(02)00079-6Frantisek Hartl...

Nanoparticles (NPs) show promising applications in biomedicine, catalysis, and energy harvesting. This applicability relies on controlling the material’s features at the nanometer scale. Surfactants, a unique class of surface-active molecules, have a re
Nature Chemistry12,242–248 (2020)Cite this article 15kAccesses 123Citations 65Altmetric Metrics Abstract Aromaticity is a vital concept that governs the electronic properties of π-conjugated organic molecules and has long been restricted to 2D systems. The aromaticity in 3D π-conjugated molecules...
The general bathochromic shift of the absorption maxima from the free ligand to the organometallic complexes has been observed for other palladium-oxazolone complexes and can be interpreted as the palladium contribution to the frontier orbitals. In the case of complex 2a, two relative absorption ...
