Current project A3 SFB 1316

Excitation transfer between molecules in transient atmospheric pressure plasmas

Aim of the project is a fundamental understanding of the excitation transfer between molecules and excited plasma species within a non-equilibrium plasma, its impact on the plasma chemistry and synergies with surface catalytic reactions. The plasma is generated by a capacity couple RF driven plasma jet with exchangeable glass plates for the introduction of different catalysts. It allows probing along the plasma channel, corresponding to different reaction times of a volume element within the plasma. The excitation and density of heteronuclear molecule within a plasma is studied utilizing FTIR. Mononuclear molecules molecules as well as excited noble gas species can be studied employing molecular beam mass spectroscopy and ionization threshold mass spectrometry, respectively.
