    • note
    • 2 manifold are optically active. This would give rise to only three, in place of five, d → s transitions with nonzero intensity. Random fluctuations in the coordination shell can however result in electronic coupling between d states, in addition to merely changing their energy. This effect was studied by diagonalizing a 5×5 Hamiltonian containing orbital energies as from Fig. 6 as diagonal elements, and including random fluctuations in the form of Gaussian distributions of width 0.06 eV. Only three states, aligned in different directions (x,y,z), were initially assigned nonzero oscillator strength. After diagonalization, all states were found to be active, and the resulting spectrum to be well described by a sum of Gaussian distributions. In the model described in the main test we therefore followed the simplifying assumption that each of the five d → s modes would contribute by the same amount to the overall ion absorption.
