Abstract : Flow-tube experiments on vibrational energy transfer from N2 to CO and NO are described. A primary flow of N2 was vibrationally excited by an S-band microwave discharge and mixed with either cold CO or NO. The first overtone band radiation from the heteronuclear molecules was spectrally resolved at selected downstream stations, and the data were compared with an analytical model computed for different number density distributions. Number density distribution measurements do not agree with either the Boltzmann distribution or with the Treanor, et al., non-Boltzmann distribution for high vibrational levels. (Author)
