Spectral measurements of high temperature 13C16O2 and 13C16O18O in the 4.3-microm region.

High resolution (0.007-cm(-1)) spectral measurements of a hot (800 K) CO(2) sample consisting of 88% (13)C(16)O(2), 11% (13)C(16)O(18)O, and 1% various other isotopes were made in the 4.3-microm region using the Air Force Geophysics Laboratory Fourier transform spectrometer. Vibration-rotation constants which predict line positions to better than 0.001 cm(-1) are presented for several bands of these two isotopes.

Aurorally enhanced infrared emissions.

Aurorally enhanced IR emissions in the 2.9-microm region have been measured from a jet aircraft with a zenith looking radiometer. Overtone chemiluminescent emission from chemically produced NO is the postulated source.
