Abstract:
Crystals of TMAMxM′1?xCl3 · 2H2O where TMA = (CH3)3NH+ and M = Mn2+, M′ = Co2+ are strikingly pleochroic. The polarized spectra of these highly colored orthorhombic salts are reported and transition assignments are made based on D2h symmetry. Peaks in the Mn(II) spectra are explained as electric dipole transitions while peaks in the Co(II) spectra are explained as magnetic dipole transitions.
