On the hyperfine coupling in tetragonal copper(II) complexes

The vibronic effect on the hyperfine coupling (HFC) parameters in tetragonal copper(II) complexes was studied. The parameters of the vibronic contributions from the - and 4s-AOs of the Cu²⁺ ion to the ground-state function were estimated. The anomalous behavior of the isotropic HFC was analyzed in terms of the static model with consideration of the vibronic coupling. The static and vibronic contributions to the anisotropic portions of the components of the HFC tensor were estimated.Translated from Koordinatsionnaya Khimiya, Vol. 31, No. 3, 2005, pp. 204–206.Original Russian Text Copyright © 2005 by Muravev.This revised version was published online in April 2005 with a corrected cover date.This revised version was published online in April 2005 with a corrected cover date.
