The infrared interferometer spectrometer (IRIS) on Voyager 2 recorded thermal emission spectra of Uranus between 200 and 400 cm-1 and of Miranda and Ariel between 200 and 500 cm-1 with a spectral resolution of 4.3 cm-1. Reflected solar radiation was also measured with a single-channel radiometer sensitive in the visible and near infrared. By combining IRIS spectra with radio science results, a mole fraction for atmospheric helium of 0.15 � 0.05 (mass fraction, 0.26 � 0.08) is found. Vertical… 
Infrared Observations of the Neptunian System
TLDR
Comparison of winds derived from images with the vertical wind shear calculated from the temperature field indicates a general decay of wind speed with height, a phenomenon also observed on the other three giant planets.
Voyager 2 Radio Science Observations of the Uranian System: Atmosphere, Rings, and Satellites
TLDR
Voyager 2 radio occultation measurements of the Uranian atmosphere suggest a new kdnd of planetary ring feature characterized by highly ordered cylindrical substructures of radial scale on the order of meters and azimuthal scale of kilometers or more.
Voyager infrared observations of Uranus' atmosphere: Thermal structure and dynamics
Observations of Uranus by the Voyager infrared spectrometer at 325 cm−1 have been analyzed to obtain the variation with latitude of temperatures near the tropopause. The lowest temperatures occur
The atmosphere of Uranus: Results of radio occultation measurements with Voyager 2
During Voyager 2's occultation by Uranus the radio link from the spacecraft probed the atmosphere of the planet at latitudes ranging from 2° to 7° south. The measurements, which were conducted at two
Voyager 2 in the Uranian System: Imaging Science Results
TLDR
Voyager 2 images of the southern hemisphere of Uranus indicate that submicrometersize haze particles and particles of a methane condensation cloud produce faint patterns in the atmosphere, and Voyager images confirm the extremely low albedo of the ring particles.

Infrared Observations of the Saturnian System from Voyager 2
TLDR
During the passage of Voyager 2 through the Saturn system, infrared spectral and radiometric data were obtained for Saturn, Titan, Enceladus, Tethys, Iapetus, and the rings, suggesting an approximate symmetry in the small-scale structure.

Atmospheric temperature profiles of Uranus and Neptune
Far-infrared spectrophotometry of Uranus and Neptune in the 30-55 micron spectral range is presented. The measurements in the present six independent spectral bands allow the derivation of
The helium abundance of Saturn from Voyager measurements
Voyager radio-occultation and IR spectroscopy measurements are combined to infer an He mole fraction in the upper troposphere of Uranus of 0.152 + or - 0.033; the corresponding mass fraction is Y =
The helium abundance of Jupiter from Voyager
The helium abundance in the Jovian atmosphere is derived from Voyager 1 data by two methods. The first method uses only infrared spectra from selected locations on the planet while the second method
Infrared spectrometer for Voyager.
The Voyager IR investigation uses a Michelson interferometer with a 4.3-cm(-1) spectral resolution in the 80-2500-cm(-1) range and a single-channel radiometer for the visible and near-IR,
