ChemInform Abstract: THE SHAPES AND ENERGETICS OF DIMERIC LITHIUM AND SODIUM CYANIDES. AB INITIO MOLECULAR‐ORBITAL CALCULATIONSstructure (organic substancesThe geometries and energies of many different isomers of (LiCN)2 and (NaCN)2 have been investigated by ab initio molecular-orbital calculations, ...
Orbital hybridization is a concept in chemistry that deals with how atomic orbitals mix to form new hybrids with varying shapes and energies. Orbital hybridization is important in chemistry because it helps chemists to understand molecular structures and predict the reactivity of different species. ...

Shapes of Atomic Orbitals Atomic orbitals have the following characteristic shapes INDEPENDENT of the value of the n or the main shell: 1. s orbitals have a spherical shape. 2. p orbitals have a dumbbell shape. There are 3 p orbitals oriented at right angles, along the x, y and z axis...
The shapes of molecular orbitals obtained by merging two atomic orbitals resemble the shapes of the atomic orbitals. When the orbitals merge to give a molecular orbital, they overlap in a region of space common to the bonded nuclei. First, consider the merger of two 1 s orbitals. Partial ...
Neutron and gamma-ray measurements were made by the NEGA instrument in an experiment on board the orbital complex SALYUT-7-COSMOS-1686. This instrument, based on CsI(T1) scintillation crystal, allowed registration of gamma-rays in the energy range 1.5–65 MeV and neutrons with energies more tha...
One of the common topics discussed in undergraduate instruction that lends itself to calculation with Mathematica is the display of shapes of atomic and molecular orbital wave functions (5). We have prepared a set of instructions within Mathematica (called a 'package') that permit computation and ...
Molecular Orbital Theory Molecular orbital theory describes covalent bonds in terms of molecular orbitals, which result from interaction of the atomic orbitals of the bonding atoms and are associated with the entire molecule. Atomic Orbital = belongs to only one atom Molecular Orbital = belongs to th...
Magneto-optical response, i.e. optical response in the presence of a magnetic field, is commonly used for characterization of materials and in optical communications. However, quantum mechanical description of electric and magnetic fields in crystals is
(r) for Li-Mg alloy are shown in Fig.1. Overall, the predicted shapes and peak neighbors of pair distribution functions by OF-DFT within NLPPF match the results calculated by KS-DFT. Especially notable are the resulting contributions of the partial distributions (Fig.1b–d) calculated by ...
