Abstract
The EMR study of Mn2+ doped potassium trihydrogen selenite is performed and the site of Mn2+ in the lattice is discussed. The zero field parameters providing good fit to the observed EMR spectra are estimated. The spin-Hamiltonian parameters g, A, B, D, and a are (2.0003 ± 0.0002), (31 ± 2) Ã 10â4, (20 ± 2) Ã 10â4, (87 ± 2) Ã 10â4, and (â9 ± 1) Ã 10â4 cmâ1, respectively. The percentage of covalency of the metal-ligand bond is also determined. The optical absorption study suggests the lattice distortion in the crystal. The electron repulsion and crystal field parameters having good fit to the observed optical spectra are evaluated. The band positions are fitted with the Racah parameters (B and C), the cubic crystal field splitting parameters (Dq), and the Trees correction (α). The values of B, C, Dq, and α are 871, 2967, 670, and 76 cmâ1, respectively.
