Abstract
Absorption spectra are reported for solutions containing Co(II) and ammonia. Spectra are calculated for five Co(II) aquoamino complexes. The spectra are used to determine Dq and B, parameters of the bonds in these compounds. It is found that Dq and B change nonlinearly and nonadditively. The parameters λc, Dt, Ds, δσ and δπ have also been established for [Co(H2O)6]2+ and [Co(NH3)6]2+. The parameter variation can be explained if the H2O molecules form weaker σ bonds to the central atom than do the NH3 molecules, but are capable of dπ-pπ interaction.
