Use the sliders to investigate the effect of a Jahn-Teller tetragonal distortion on the splitting of t_2g and e_g orbitals and on the spin allowed transitions of a d¹, high spin d⁴, high spin d⁶ and d⁹ ion. Positive splitting corresponds to a tetragonal elongation (along the z-axis) and negative splitting corresponds to a tetragonal compression (along the z-aixs) of an octahedral complex. In real complexes, the splitting of the e_g orbitals is usually much bigger than that of the t_2g orbitals.

Each band has been arbitarily given an intensity of 100 but the effect of band overlap can be investigated using the 'relative width' slider.
