In the course of its research, the group studies the electron configuration of transition metal compounds that have special conduction and  excitation properties, chiefly using  X-ray spectroscopic techniques based on synchrotron radiation. The major systems examined are oxides with strongly correlated electrons and the functional molecules that have a great importance and potential in molecular switches, solar energy use, photo-catalysis and molecular biology. In addition to static examinations, we have recently been making an important effort to use the methods of X-ray spectroscopy for examining the dynamics of electronic and molecular structures, applying them as probes in femtosecond time-resolution experiments.

The subsidy won in 2013, in the framework of the MTA Lendület programme , provides the opportunity for new research, enabling us to set up a femtosecond transient optic absorption installation in the HELIOS laboratory of the research center, in collaboration with the Ultra-fast, highintensity light-material interactions group. This installation offers new possibilities for exploring the elemental steps of the transformations of functional molecules.
