Welcome to the homepage of the research group!
 One efficient way to study the properties of molecules, their reactions and reaction intermediates is to isolate these species as impurities in an inert solid environment, for example, in solid rare gases or nitrogen. Such low-temperature (4-50 K) samples are probed by various spectroscopic methods like FTIR or Raman spectroscopy and time-resolved laser-induced fluorescence (LIF). The photochemical processes are initiated at wavelengths varying from vacuum UV to mid-infrared by using different lasers and a tunable narrowband optical parametric oscillator.

Computer-assisted research on ground and excited state properties of the precursors, decomposition pathways, interactions with the surrounding, and the properties of the photoproducts are of our interest. Our ultimate goal is to combine experimental and computational techniques in order to obtain the maximal advantage of both approaches. This synergism we hope to expand our understanding of the nature and its vivid variations.
