This report describes the research efforts of the past three years centered around measurements made on the LABCEDE Facility at the Air Force Geophysics Laboratory. Chapters 2 and 3 are concerned with fluorescence arising from beam created CO in irradiated CO2Ar mixtures. The two dominant sources of radiation observed in these mixtures are the CO2v2 band at 4.3 micron and the fundamental vibrationrotation band of CO. The CO emission arises from highly vibrationally excited levels up to v 19 occurring in an extremely non-Boltzmann vibrational distribution. From a related kinetic analysis, predictions of the efficiency of creating vibrationally excited CO in these mixtures is discussed in Chapter 3. Chapters 4 and 5 deal with NO fluorescence arising from electron irradiated N202 mixtures. The relaxation of NO in N202 mixtures is described in Chapter 5. A study of the cryogenic LABCEDE facility is found in Chapter 6. A preliminary survey of the emission from N2, 02, and N202 gas mixtures in the spectral region 0.6-3.0 micron has been completed using both the interferometer and a 14 meter spectrometer and these findings are given in Chapter 7. A variety of gas mixtures were irradiated in search of a strong radiation in the 3-4 micron region. The results of this survey are presented in Chapter 8. The magnitude of various noise sources and their effect on the transformed spectra are discussed in Chapter 9, along with our findings of the effects of interferometer alignment on spectral intensities.
