Abstract
The gadolinium chelates with: acetylacetone-Gd(acac)(3) . 3H(2)O, then oyltrifluoroacetone-Gd(TTA)(3) . 2H(2)O, benzoylacetone-Gd(BAC)(3) . 2 H(2)O, ethylenediaminetetraacetate Gd(EDTA) and diglycolate Gd(DGA)(3) have been chosen for EPR study (X band). The EPR spectra of these com plexes were obtained in the form of badly separated signals acid thus were difficult to interpret. In order to improve the spectra resolutio n a computer analysis based on Fourier transform was applied. This ana lysis permitted a considerable increase in resolution of the spectra a nd revealed the fine structure of Gd3+ ion in the condensed phase.
