Sammanfattning

Photoexcited states of a pyrazolate bridged PtPt dimer and a supramolecular RuCo complex with bipyridine-type ligands were studied using the pump-and-probe X-ray absorption spectroscopy method. The local structure refinement based on the fitting of XANES difference spectra has been performed. The theoretical analysis included the full multiple scattering calculations and the multidimensional interpolation of spectra as a function of structural parameters. The influence of possible correlations between the fraction of molecules in the photoexcited state and structural parameters is discussed. (C) 2011 Elsevier B.V. All rights reserved.
