Abstract:
The performance of some kinetic energy density (tau) dependent functionals in predicting the effective Heisenberg exchange has been explored using the KNiF3 and K2NiF4 insulators as case examples. Our results show that this new generation of functionals represents an important improvement with respect to the current local and gradient corrected functionals yielding a semi-quantitative description of the antiferromagnetic coupling without the need of hybrid approaches thus avoiding the calculation of exact, Hartree-Fock exchange. This feature opens a wide field of application especially in solid state.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
