Understanding Molecular Orbitals; Sigma Orbitals

Various plots of sigma molecular orbitals in diatomic molecules are discussed.

Triatomic Molecular Orbitals

If elementary Quantum Chemistry stops at diatomic molecules, some students may be left with false impressions concerning how one builds polyatomic molecule's LCAO-MOs. This reading discusses building such molecular orbitals from atomic orbitals centered at different spatial coordinates.
