An infrared spectrometer used to obtain atmospheric emission spectra from a rocket at altitudes between 45 and 200 km in the ICECAP Auroral Measurements Program is described. The instrument continuously scanned the 6.75-23.2 micrometers spectral region at the rate of 2 scans per second. The instrument resolution of the spectrometer, which employed a circular-variable interference filter CVF, ranged from 3 to 4 percent.
