Electronic spectroscopy of flavins in a cryogenic 22 - pole ion trap
… tandem mass spectrometer coupled to a cryogenic 22 - pole ion trap and an electrospray ionization source. Here, the first high-resolution vibronic spectra of protonated and alkali metalated flavins isolated in the gas phase are reported. A joined approach of quantum chemistry and cryogenic ion …

Internal Excitations of Stored Triatomic Hydrogen Molecular Ions
… For future experiments, a cryogenic 22-pole ion trap was constructed, which is capable of preparing rovibrationally cold H3+ ions.

Construction And Demonstration Of A Tandem Mass Spectrometer Based Instrument For Cold Ion Spectroscopy
… ions. The instrument incorporates multiple quadrupole linear ion trap mass analyzers to prepare and isolate the precursor ions as well as to analyze the resultant photofragments. A 22-pole ion trap cooled to 5 K via a closed cycle helium cryostat is used to cool the ions for spectroscopic …

On the Chemistry of Molecules Containing Silicon, Phosphorus, and Sulfur in the Interstellar Medium
… collected by IR-action spectroscopy, using the 22-pole cryogenic ion trap FELion. Next projects regard the investigation of the gas-phase reactivity of HCCS+. Reactivity occurs not only in the gas phase, but also on solid icy grains of interstellar dust and debris. Although the dusty material …
