• (International Symposium on Molecular Spectroscopy, 2021-06-23)
Strong vibrational nonequilibrium is sustained in nitrogen and nitrogen/carbon dioxide “hybrid” plasmas, generated by a ns pulse train overlapping with a sub-breakdown RF waveform. \chem{N_2} vibrational level populations ...

• (International Symposium on Molecular Spectroscopy, 2021-06-23)
Vibrationally excited oxygen and nitrogen have been long recognized to be of critical importance in nonequilibrium high-enthalpy flows, primarily encountered behind hypersonic shock waves. To date, no direct experimental ...
