Sažetak
The electron paramagnetic resonance and optical absorption spectra of Rochelle salt doped with CuCh and Cu(CH3C00)2 have been measured in the paraelectric, ferroelectric and antiferroelectric states. Both ways of doping lead to similar EPR spectra consistent with. the assumption that the Cu2+ replaces the Na+ ion. From the optical absorption data the bonding parameters of copper to the ligand oxygens and the theoretical Kcx and g!f!f values were calculated. On passing the lower Curie point, the EPR lines of the A Cu2+- ions site show a significant shift with regard to the slight shift of the B site lines, while on passing the upper Curie point the lines of the B site are more shifted than those of A site.
