Abstract

Since the first experimental confirmation of axial Jahn-Teller effect in Cu(II) doped ZnSiF6.6H2O in 1950, the Orthorhombic Jahn-Teller Effect (OJTE) in solids has not been clearly observed experimentally even though a lot of conjectures have been made. This is the first report of experimental observation of orthorhombic Jahn-Teller EPR spectra 2E Cu(II) ion in cadmium ammonium sulphate crystal providing the direct confirmation of the OJTE. The spectra correspond to all the three Jahn-Teller potential well minima being non-equivalent in energy. The detailed theoretical analysis (not reported here) of the spectra led to evaluation of many spectroscopic parameters and their temperature dependence, suggesting potential applications of such systems.
