The dichroism in the visible and ultraviolet region has been quantitatively determined at room temperature by Tsuchida and Kobayashi’s microscopic method with a single crystal of d, l-[Co en3] Cl3·3H2O, d, l- [Co en3] Br3·3H2O, d- [Co en3] Br3·2H2O and d, l-[Cr en3] Cl3·3H2O.It has been found that the [Co en3]3+ and the [Cr en3]3+ ion show a similar type of dichroism. For both the complex ions, the z-absorption is slightly stronger than the x-absorption in the wavelength region of the first absorption band and much weaker than the x-absorption in the region of the second absorption band.The results of the measurements are discussed in relation to the electronic state and the optical rotatory dispersion of the complex ions.
