Key Points

Vibrational excitation and relaxation dynamics vary significantly with gas composition in flame plasmas, impacting overall efficiency.
Analysis of N2, O2, and CO2 under pulsed microwave conditions shows that vibrational energies are influenced by specific molecular interactions.
The study employs a molecular dynamics approach, utilizing computational simulations to illustrate energy transfer processes in plasmas.
Results support the need for optimized gas compositions to enhance energy transfer in industrial applications of flame plasmas.
