| Abstract: | A spectrum of Saturn obtained from the Kuiper Airborne Observatory exhibits an emission peak at 6.8 μm attributed to ethane, but is otherwise dominated by absorption from 5.3 to 7.2 μm. While the large absorption in this spectral region is consistent with the presence of ammonia gas or ammonia ice, or both, such an explanation is inconsistent with the lack of a major absorption near 3.0 μm. |
