Absorption Spectrum of Mn2+ in KCl

Abstract

The absorption spectrum of an Mn²⁺‐doped KCl crystal has been measured at room temperature. The observed bands are assigned as transitions from the ⁶A₁(S) ground state to various excited quartet levels of a Mn²⁺ ion in a cubic crystalline field. The observed band energies are fitted with four parameters B, C, Dq, and α and the values obtained for the parameters in cm⁻¹ are B=760, C=2955, Dq=590, and α=76.
