Research

We explore ultrafast electron dynamics of photoexcited molecules using time-resolved photoelectron spectroscopy. The main goal of the program is experimental investigation of the influence of molecular environment on the excited state relaxation dynamics of biochromophores and biomimetic systems. The experiments are conducted using recently constructed XUV time delay compensating monochromator beamline coupled to a photoelectron spectrometer with a microliquid jet sample delivery system. This setup allows recording photoelectron spectra of relaxing molecules in their natural environment: water, other solvents or protein cages. The setup is also used in combination with the velocity map imaging spectrometer to investigate gas phase molecular dynamics using time-, energy-, and angular-resolved photoelectron spectroscopy.
