Modeling of X-ray K-absorption parameters of cobalt (II) complexes with Wiener indices

An application has been used in modeling the. X-ray absorption parameters. The use of Wiener index (W) for estimating, predicting and comparing the X- ray K-absorption parameters of some cobalt (II) complexes of a series of be nzohydroxamic. acid ligands has been described. The K-absorption parameters used are chemical shift (DeltaE(K)), fractional oxidation number (Z(eff)), shift of principal absorption maximum and edge-width for this purpose. The results obtained with regression analysis of the data show that Wiener ind ices (W) can be successfully used for estimating these parameters.
