| Abstract: | The multiphonon sideband of the spin allowed transition 6T2g:A1 ? 2〉 → 6Eg:B3 ? 2〉 within the 3d6 orbital of Fe2+ in D2h symmetry was analyzed with respect to the one phonon absorption and density of states of the coupled phonon modes. Temperature dependence of the zero-phonon line shows, that the axial anisotropy of the S = 2 spin multiplet in the excited B3 state is about 0.9 cm-1. |
