Title: Spectra of Uranus and Neptune at 8-14 and 17-23 microns

Abstract

The 3-m NASA Infrared Telescope Facility was used to observe the disks of Uranus and Neptune between May 30 and June 1, 1985 in the 7-14 and 17-23 micron spectral regions. Maximum stratospheric mixing ratios of 9 x 10 to the -9th for C/sub 2/H/sub 2/, and of 2 x 10 to the -8th for C/sub 2/H/sub 6/, are found for Uranus, and the spectrum is otherwise smooth, consistent with the opacity provided by H/sub 2/ collision-induced absorption and spectrally continuous stratospheric emission. Strong emission features of CH/sub 4/ and C/sub 2/H/sub 6/ are found in the short-wavelength spectrum of Neptune, and the spectrum near 13.5 microns is consistent with C/sub 2/H/sub 2/ emission in local saturation equilibrium with a maximum mixing ratio of 9 x 10 to the -7th. 27 references.
