Description
The polarized crystal spectra of a series of tetragonal
trans- diacidobis (ethylenediamine) chromium (III) complexes, trans-[Cr(en)2XY], where X= Y = Br-, H2O, F-, Cl- and X= H2O, Y = OH-, F-, have been measured at liquid nitrogen temperature,
achieving better resolution of the split components of the cubic spin-allowed
bands, and also definite energy level assignments. The
observed band positions have been fitted with the predicted transition
energies by the use of the appropriate energy equations for d^3 configuration
immersed in tetragonal fields with full configuration interaction.
The ligand field parameters, which include the cubic and axial, and the
electron correlation parameter B have been evaluated by such a fitting.
The derived parameters have been analyzed and their significance discussed.
Using thick crystals, we have uncovered a rich doublet
structure in some of the complexes and tentative values of the electron
correlation parameter C have been obtained for all the complexes.
