molecules and radicals are important species in combustion processes.
But the investigation of their spectroscopy and dynamics in high temperature
environments is often not feasible with conventional laser techniques
due to congested spectra.
Furthermore, the characterization of transition metal clusters is crucial in order to gain better insights into catalytic systems.
The goal of the molecular beam facility at the
PSI is to generate vibrationally and rotationally cold polyatomic molecules, (metallic) clusters,
and radicals that are suitable for their spectroscopic investigation.
We use an advanced non-linear technique in combination with more conventional methods
for the measurement of these species in the controlled environment of the molecular beam.
The production of specific transient species in the molecular beam is achieved by laser-vaporization of metals and by
pyrolytic, photolytic or discharge sources.
