AN EXPLANATION OF THE SPECTRAL SPLITTINGS OF CsMnBr3 WITH CRYSTAL FIELD OF LOW SYMMETRY
低对称畸变晶场下晶体CsMnBr3吸收光谱分裂的理论解释

Considering distorted octahedral crystal field-D3d point group symmetry of Mn2+ ion in CsMnBr2, crystal and using Zhao's SCF d-orbit of Mn2+ in complex, we have investigated electronic structure and absorption spectra of Mn2+ in MnBr64-. The spectral splittings at 18280cm-1, 21700cm-1, 26300cm-1, and 29650cm-1 have been interpreted by low symmetry crystal field. The theoretical calculations are in good agreement with experiment
