Scf Calculations

We have performed self-consistent field (SCF) calculations of the electronic structure of GaAs/Ga 1-x Al x As superlattices with parabolic potential profile within the effective mass theory. We have calculated the optical transition matrix elements involving transitions from the hole states to the electron states, and we have also computed the oscillator strength matrix elements for the transitions among the electron states.

Scf Calculations

The electrostatic energy of an atomic state arising from a configuration involving holes differs by ΔW from the energy expression of the same state arising from the configuration involving electrons where ΔW can be expressed in terms of Slater's integrals.General formulas for ΔW are given for the pmfq and dnfq configurations. In addition, the vector-coupling (VC) coefficients useful for atomic self-consistent field (SCF) calculations are presented for all the states arising from the pmfq and dnfq configurations.

Scf Calculations

The π-electron densities, bond orders, free valences, and reactivity indices according to Fukui's “frontier orbital”-model were calculated for all reactive centers of porphin, chlorin, bacteriochlorin and phlorin by means of Self Consistent Field (SCF) calculations using the approxima tiaons of Pariser, Parr, and Pople. The results were compared with known experimental facts. The relative reactivities of different reactivity centers (e. g. methine-bridges and β-pyrrolic carbon atoms) are well predicted by calculated π-electron densities, whereas the characteristics of similar reactivity centers (e. g. the different methine-bridges in chlorin) are better reflected in the reactivity indices of the “frontier orbital’ model. Reasons for the partial inadequacies of the models used are shortly discussed.
