Original Abstract

The effect of the nitrogen pink afterglow quenching by hydrocarbon traces is studied in the flowing afterglow regime. The Pyrex wall temperature around the observation point was varied between the ambient and liquid nitrogen temperature. The spectra of nitrogen first and second positive and first negative bands and CN violet and red systems were observed. The strong quenching of the vibrational populations of the nitrogen N2(B), N2(C) and N2+(B) states was observed and this effect increases with the decreasing wall temperature. The vibrational populations of CN(A) and CN(B) states are more or less independent of the hydrocarbon concentration at the ambient wall temperature, but they increase with the decreasing temperature. A simplified kinetic model of the processes at our experimental condition is presented, too.
