Vibronic averaging effect in ESEEM spectra of (NH4)(2)Mg(SO4)(2)center dot 6H(2)O single crystal doped with Jahn-Teller active Cu(H2O)(6) complexes
Vibronic behavior of the Cu(H2O)(6)(2+) in (NH4)(2)Mg-(SO4)(2). 6H(2)O is not a local phenomenon but involves surrounding molecular groups forming a vibronic cluster. It is observed by temperature variations of the Fourier transform spectra of electron spin-echo decay.
