The video conferencing program of family and consumer sciences (FCS) is into it's fifth year offering 18 programs a year throughout U.S. Along with the interactive video conferencing technology, the students are also encouraged to use computers, video cams, and digital equipments through hands-on learning project.

Coupled Hartree–Fock calculations of electric and magnetic properties of the isolated closed-shell permanganate anion show it to be paramagnetic, in agreement with experimental measurements on KMnO4. Lattice effects on the computed value are small, but the computed paramagnetizability is highly sensitive to changes in the Mn–O bond length, moving from near perfect agreement with the estimated experimental value of ξ p=75.9 a.u. for the self-consistent-field bond length (R=2.93 a0) to over twice that value at the experimental distance (R=3.078 a0). Analysis of the perturbed wave function leads to a physical rationalization of the anomalous sign of the magnetizability: Ligand-field splitting of the Mn d valence space leads to near-degenerate occupied and virtual orbitals coupled by induced 2-center σπ rotations. The improvements in magnetic properties that would result from use of a valence complete active space wave function are discussed. [ABSTRACT FROM AUTHOR]

The study and analysis of the patterns of current flow in localized orbitals shows that a magnetic criterion for the physical significance of an orbital is that it should support closed flowlines of current density and the ipsocentric formulation of the theory of current density is extended to provide a visualization of the pattern of current flow in system with several centers of circulation. The number of electrons counted as contributing to the current density is related to the degree of localizability of the electron distribution.
