The Zeeman g-factor, axial zero-field splitting parameters and rhombic zero-field splitting parameters of Fe3+ ion in DPSC are determined with the help angular dependence of EPR spectra. Fe3+ ion enters the crystal lattice substitutionally replacing the K+ ion. The optical absorption spectra are recorded at room temperature in the wavelength range 195-1,100nm. The transitions are assigned from the ground state $${}^{6}{\text{A}}_{{1{\text{g}}}} \left( {\text{S}} \right)$$ 6 A 1 g S to different excited states of Fe3+ ion. The observed band positions fitted by four parameters, Racah inter-electronic repulsion parameters (B and C), cubic splitting parameters (Dq) and Trees correction (α) yield: B=831cm−1, C=2,198cm−1, Dq=820cm−1, and α=90cm−1.
