Molecular Spectroscopy and Chemical Kinetics Group studies at the IUP, University of Bremen are:

to provide accurate reference spectra to be used in atmospheric remote sensing using and satellite spectrometers,

to provide rate coefficient reference data needed to determine absolute cross sections of relevant atmospheric species,

to determine atmospheric trace gas concentrations using optical methods,

to study molecular physics and chemistry related to atmospheric problems,

and - in close co-operation with the corresponding agencies and industrial facilities - the on-ground calibration of satellite spectrometers as done for GOME-1 and SCIAMACHY.

The technique in general is absorption spectroscopy: the interaction of light with atoms and molecules. In more detail the activities cover:

High resolved UV/VIS/NIR Fourier Transform Spectroscopy (FTS); Time resolved UV/VIS/NIR Fourier Transform Spectroscopy (TR-FTS);

High speed time resolved UV/VIS absorption spectroscopy using flash photolysis combined with a modern fast CCD time resolved detection set-up;

Time resolved VUV/UV resonance absorption spectroscopy of atomic species;

High resolved UV/VIS/NIR monitoring of atmospheric trace gases using Fourier Transform Spectroscopy (SOCCER);

Mobile gas handling and optical absorption set-up for direct on-ground trace gas absorption measurements with satellite flight models (CATGAS);
