Combination of experiments and numerical modeling of equilibrium field configurations, with a subsequent spherical harmonic expansion, allows us to systematically probe elastic multipole moments, bringing analogies with electromagnetism and structure of outmost occupied shells of atomic orbitals. We show that,...
We present the molecular orbital as a linear combination of atomic orbitals (LCAO) [52,55], ∑𝑠∑𝑎𝑐𝑠𝑎𝜓(0)𝑎(𝐫+𝑠𝐑0/2), where 𝐫 is the relative electron coordinate and 𝐑0 is the equilibrium internuclear distance. We use the Born–Oppenheimer approximation [55...
In the molecular orbital theory, two atomic orbitals of valence electrons of similar energy and orientation form a bond. Molecular orbital arises from two atomic orbitals, which have to be conserved. So, there is a bonding orbital and an antibonding orbital. The bonding orbital is a three-dimen...
Atomic level broadening near metal surfaces: Inclusion of hybridization effects in first-order calculations The interaction of slow atoms and ions with metal surfaces results in a hybridization of the atomic orbitals as well as a shift and a broadening of the ass... U Wille - 《Nuclear Instrumen...

a A schematic figure describing the unit cell and the relevant atomic orbitals of a monolayer graphdiyne (MGD) composed of 18 carbon atoms. Two sublattices are marked with yellow and blue colors, respectively. Since MGD has a bipartite lattice structure, chiral symmetry exists when only the near...
What is the energy of the electron in the ground state of a He+ ion? Which orbital or orbitals is/are specified by the set of quantum numbers n= 4 and l= 3? What is the charge of a bare Magnesium nucleus (no electrons, just the protons, and neutrons) in Coulombs?
The basis sets used are primarily pseudo-atomic orbitals (PAOs), generated by a utility provided in the package. The PAOs can be used as primitive basis sets, and as basis functions for multi-site support functions (MSSF) to allow large-scale diagonalisation calculations (up to several thou...
