Understanding Molecular Orbitals; Sigma Orbitals

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

Butadiene via the Huckel Scheme (using Maple)

The Huckel Molecular Orbtial method is used to treat the MO's of butadiene. The method employs analytical tools and Maple.

Variational Calculation of the Hydrogen Molecular Cation using Maple (II). The pi and pi-star Orbitals

The pi and pi-star orbitals of the hydrogen molecular cation are obtained using Maple in the same manner as the sigma and sigma-star orbitals were obtained in paper-36.

Variational Calculation of the Hydrogen Molecular Cation Using Maple

The variational calculation of the energy of the Hydrogen Molecular (H2+) Cation's LCAO-MO for the sigma and sigma* states as functions of the AO's screening constant and the internuclear distance is carried out explicitly in great detail.
