| Abstract: | The electronic absorption spectra in two polarizations are reported for crystals of the dichroic salt, TMAMnxCu1?xCl3·2H2O where TMA represents the trimethylammonium cation, (CH3)3NH+. Although TMACuCl3·2H2O is monoclinic, the mixed metal salts in which x ≥ 0.20 adopt the orthorhombic structure of TMAMnCl3·2H2O. The bands observed in the near ir region are adequately explained as d-d transitions of the Cu(II) ion in D2h symmetry. Other polarized bands which occur in the visible region and are neither Mn(II) nor Cu(II) d-d transitions are discussed. |
