The high-energy intraconfigurational spin-forbidden bands in the spectra of quadrate chromium(III) complexes

摘要

The high-energy intraconfigurational spin-forbidden bands expected in the region of 20000 cm(-1) have been uncovered in the spectra of a number of trans-diacidobis(ethylenediamine) chromium(III)complexes. These bands have been fitted to the quadrate components of the cubic transition (4)A(2g)-> T-2(2g) including spin-orbit interaction. Two interconfigurational spin-forbidden bands in the spectrum of trans-[Cr(en)(2)(dmf)(2)](ClO4)(3) have been uncovered and interpretted. (C) 2007 Elsevier B.V. All rights reserved.
