Molecular Orbitals of Heteronuclear Diatomics

Molecular Orbitals of Heteronuclear Diatomics

Molecular Orbitals of Heteronuclear Diatomics. The molecular orbitals of heteronuclear diatomics (HF, CO, CN - , etc.) can be predicted using the same principles that we used to construct the molecular orbitals of homonuclear diatomics : i ) Ignore the core electrons

s and p Bonds MO Theory

s and p Bonds MO Theory

s and p Bonds MO Theory. MO Theory: s orbitals. s orbitals form s and s * molecular orbitals Add and subtract orbitals to get the bonding and anti-bonding orbitals Start with 2 atomic s orbitals end with 2 molecular orbitals.

Graphical Models

Graphical Models

Graphical Models. We will examine a number of useful graphical models including - molecular orbitals - electron densities - spin densities - electrostatic potentials - local ionization potentials Spartan makes generation of such graphical models straightforward (via the “Surfaces” menu).

Atomic and Molecular Orbitals

Atomic and Molecular Orbitals. Structure and Properties of Organic Molecules. Electrons act as both particles and waves (duality) An orbital can be described as a 3D standing wave To understand this, we can look at wave properties of guitar strings. Wave Harmonics with Dr. Jimi.

Molecular Orbitals : combine atomic orbitals (AOs) from all the atoms in a molecule into the same number of molecular orbitals. MOs have different shapes, sizes, and energies, and have two electrons max. per orbital (Pauli Exclusion Principle).
