The electronic absorption spectrum of the spherocrystal of bellingerite 3Cu(IO3)2·2H2O, was measured, two strong absorption bands appeared at 9140 cm-1 and 15250 cm-1. The low-symmetric crystal field splitting, which is as great as 6110cm-1, was observed for the first time. Resolving the absorption curve, we obtained 8 Gauss-type absorption peaks at 8590, 10690, 10870, 12190, 13500, 14510, 15330 and 16500 cm-1, respectively. By analyzing its EPR spectrum, we got g=2.141±0.004. The experimental results were discussed quantitatively using the ligand field theory and the radial wave function, of nonfree copper(II). The calculated values were in agreement with the experimental results. Thus the electronic structure of bellingerite crystal was interpreted comprehensively.
