Abstract
During the presentation I will discuss the development of two diagnostics to increase our current level of
understanding of the vibrational kinetics within CO2 discharges, with the intention to ultimately
contribute to a controlled and efficient dissociation process. The diagnostic techniques are (1) time
resolved in situ Fourier transform infrared (FTIR) spectroscopy and (2) spatiotemporally resolved in
situ rotational Raman spectroscopy. Both techniques are used to obtain information about the rovibrational
density distributions in the electronic ground state of CO2 in a pulsed glow discharge. During
the active part of the plasma pulse a clear non-equilibrium is observed between the rotational and the ν3,
and the (ν1, ν2) and ν3 vibrational density distributions. The results provide ample experimental
foundation to expand our knowledge on CO2 vibrations and dissociation, especially through comparison
with numerical models.
