State-to-state modeling of a recombining nitrogen plasma experiment

► Nonequilibrium recombining nitrogen plasma at atmospheric pressure. ► Measured vibrational population distributions in the N2 B, N2 C, and N2+B states. ► Showed non-Boltzmann vibrational distribution for the N2 B state. ► Developed state-to-state model to predict vibrational population distributions. ► Proposed way to measure N atom density using emission of predissociating N2 B state.
