We investigated the optical properties of Co^{2+} cations in the aqueous and alcoholic solution of CoCl_2·6H_2O at room temperature. We measured the absorption spectra of these solutions in the spectral region 395-800 nm. The Racah parameters and the exchange integrals of the aqueous complex [Co(H_2O)_6]^{2+} are calculated. The parameters D_{t} and D_{s} are also calculated on the basis of our experimental data. The parameters δ σ and δπ which are connected with the symmetry of this complex are also determined.
