Fundamental Rovibrational Excitation in Co2 Low‐Temperature Plasma in the Presence of Common Impurities

Year: 2025

Type: article

Abstract: ABSTRACT The interactions in plasma recycling are simplified by limiting the excitation of mixtures with or to rovibrations in a low‐temperature glow discharge. In situ infra‐red absorption spectroscopy measures rovibrational temperature trends, analysed for collisional energy transfer. With , symmetric vibrations of show temperature behaviour similar to the asymmetric stretching due to the change in dominance from excitation to relaxation. Adding delays discharge onset, likely because the electronegativity of hinders electron avalanche formation. Both datasets aid in benchmarking kinetic models.
