Abstract
EPR and optical absorption spectra of copper-doped zinc potassium phosphate
hexahydrate (ZPPH) are recorded both at room temperature and liquid nitrog
en temperature. Both, EPR and optical spectra are characteristic of Cu(II)
ion in rhombically distorted octahedral symmetry. Spin-Hamiltonian and bond
ing parameters have also been evaluated as follows: g(1) = 2.372; g(2) = 2.
188; g(3) = 2.032; A(I) = 78 x 10(-4) cm(-1); A(2) = 48 x 10(-4) cm-1. A(3)
= 63 x 10(-4) cm(-1): alpha(2) = 0.55.
