Sažetak
Copper(II) complexes with amino acids serve as models for metalloproteins and transport types of copper which are involved in a wide range of important biological processes. Therefore, the dynamical behavior of copper(II) bis-complexes with selected chiral amino acid (nonpolar, polar and electrically charged) was studied by electron paramagnetic resonance (EPR) spectroscopy. The EPR spectroscopy is technique with a long history of the study of copper(II) complexes [1]. The cis and trans isomers were confirmed by simulation of EPR spectra for both L - and D - enantiomers [2]. The pulse EPR measurements allow faster differentiation of cis and trans isomers The activation energies of rotation motion and rotation correlation time between L- and D- enantiomers obtained by simulation of CW-EPR spectra of copper(II) complexes with the same amino acids show no difference. Relaxation measurements allow differentiation of isomers dynamics.
