| Abstract: | The E″g(2T2g) å U′g(2T2g) transition of Ir4+ in Cs2ZrCl6 is observed in the infrared energy range 5000–6000 cm?1 by absorption and magnetic circular dichroism spectroscopy. The resolved vibrational structure provides detailed information about the change in vibrational frequencies on excitation and the transition intensity mechanism. The energy of the transition requires the Ir4+ spin-orbit coupling parameter ζ to be ≈ 2800 cm?1. |
