A simple, but general model which enables prediction of the electronic structure adopted by ad n ion in an axially distorted octahedron of ligands (D 4h) is described. The variousd n configurations (n = 1 to 9) are briefly reviewed with some recent results concerning the stabilization of unusual electronic configurations or oxidation states in oxides.

The long-term and excessive use of organophosphorus pesticides (OPs) leads to hazardous residues in the environment, which threatens human health to a considerable extent. Colorimetric methods can quickly and readily identify pesticide residue, but they still have various challenges in accuracy and stability.

Starting from the model of a single d-electron in an octahedral crystal environment, the Hamiltonian for linear and quadratic Jahn-Teller (JT) coupling and zeroth order as well as linear spin-orbit (SO) coupling in the 2T2g + 2Eg electronic multiplet is derived. The SO coupling is described by the microscopic Breit-Pauli operator.
