Instrumentation and Methods

Experimental Systems:

The group operates cutting-edge instruments and develops new experimental solutions that bridge between ideal ultraclean environments and true operation conditions (high-pressure, solid/liquid, electrochemical, photoelectrochemical environments).

UHV Molecular Beam IR Spectroscopy

We operate a molecular beam / spectroscopy / reactor experiment, which allows performing complex kinetic experiments in a quantitative, reproducible and fully remote-controlled fashion. Among other facilities, the system includes:
