    • Abstract

       

      The polarised single crystal spectrum of bisethylenediamine copper(II) thiosulfate is reported. The three observed absorption bands at 19.10 kK, 15.60 kK and 14.30 kK have been assigned as dxy → dxz, dyz;$$d_{xy} \to d_{xz} ,d_{yz} ;d_{xy} \to d_{x^2 - y^2 } $$ and$$d_{xy} \to d_{z^2 } $$ transitions withD4h as the symmetry of the complex ion. However the polarisation of the observed bands can also be accounted by the point group (C2h) of the complex ion. The failure in the detection of all the four bands may be due to bad orientation of the molecules in the unit cell, which also makes the ground state assignment ambiguous.
