Beschreibung:
<jats:p>Electron paramagnetic resonance studies have been made on Ag2+ ion in Na2Zn(SO4)2⋅4H2O single crystals at 300 K. Ag2+ is obtained by the x irradiation of Ag+ doped samples at ambient temperature and is found to be stable over a period exceeding one year. The EPR spectra indicate the presence of dimeric divalent silver species with the hyperfine structure with two inequivalent silver nuclei. The Ag–Ag has a singlet ground state concluded from the spectra vanishing around 100 K. The major contribution to the fine structure tensor is found to be from spin–orbit coupling.</jats:p>
