Abstract
A high resolution (λ/Δλ~104 Michelson interferometer has been used on NASA’s AIRO (C-141) telescope in November-December 1975 to observe far infrared emission lines from HII regions. The instrument operates in the rapid scanning mode under computer control and high resolution spectra are computed, averaged and displayed on-line. Observations were made in the range 17.5–20µm and 70–100 µm, with spectral resolutions of 0.03 and 0.02 cm-1 respectively, on the Orion Nebula and Jupiter. Emission spectra of the stratosphere were also obtained in these wavelength ranges. Emission from SIII at 18.7µ has been detected in the Orion Nebula. The intensity of this line is discussed compared with theoretical predictions. Preliminary results concerning the observations of OIII (88µ) in the Orion Nebula are also presented.
