A rotational Raman study under non-thermal conditions in a pulsed CO2glow discharge

“…Recently, we published work on time-resolved Fourier transform infrared spectroscopy (FTIR) in a pulsed CO 2 glow discharge [16], focussing on the vibrational excitation of CO 2 and CO. Dissociation efficiencies in glow discharges are expected to be low and difficult to determine with meaningful precision, though the discharges are well-defined and information on the time-dependent vibrational excitation serves well to verify (reaction rates in) numerical models. While others already reported vibrational excitation in similar discharges, both continuous [17][18][19][20] and pulsed [21], we were able to demonstrate the temporal development of rotational and vibrational temperatures of CO 2 and CO. These results have already been employed by Silva et al [22] for comparison and validation of a kinetic model of a CO 2 discharge.…”

Time evolution of vibrational temperatures in a CO2glow discharge measured with infrared absorption spectroscopy

“…] ), while the anharmonic part is scaled with the translational temperature. In equation (10) the translational temperature is substituted by T rot , under the previously made assumption that these temperatures are equal. When for thermal gas ] ), chosen such that all levels up to at least 6eV are included in the calculation.…”

“…A promising route for this dissociation process is through selective excitation of the asymmetric stretch vibration of CO 2 in a non-equilibrium plasma [5][6][7]. Studies on vibrational excitation of CO 2 are often done in the field of CO 2 lasers, reporting vibrational temperatures which are elevated with respect to the translational temperature [8][9][10][11]. These measurements are performed in continuous glow discharges, determining vibrational excitations depending on e.g.…”

“…Vanadates have garnered significant attention due to their versatile structural chemistry, enabling them to adapt to various structural configurations, including octahedral coordination, square-pyramidal, and tetrahedral arrangements, spanning multiple oxidation states. − These vanadate compounds have found utility across a spectrum of fields, including catalysis, electrochemistry, , optical laser applications, and biology, to name a few. , The vanadate compounds have been intensively researched in multifunctional optical applications, such as LEDs, thermo luminescent detectors, luminescence pointers, lasing media, and scintillators. − Among the various vanadates, zinc vanadate (Zn 3 V 2 O 8 , ZVO) stands out as a particularly intriguing material of interest. Zinc is eco-friendly, abundant, and cost-effective in nature, and combined with vanadium’s ability to exist in numerous valence states, gives rise to diverse architectures within its composites.…”
