Abstract

In this work, the Lorentz curves of the crystal MgSO3.6H2O:Co and aqueous solutions of CoCl2.6H2O, CoSO4.7H2O are presented. The absorption spectra α(λ) of the complex [Co(H2O)6]2+ in three aqueous solutions of CoSO4.7H2O (1%, 1.5%, 2%) are measured in spectral region 2.07 – 3.1 eV. The first and second derivatives of α(λ) are calculated. The Fermi energies of cobalt levels are also calculated.
