摘要：

We derive a new estimate of the arsenic abundance in Jupiter from ground-based and airborne observations in the region of the AsH3 Q-branch at 2126 cm-1. We used newly analyzed laboratory comparison spectra at AsH3 to determine that the mole fraction of AsH3 in Jupiter's atmosphere is 0.22 ± 0.11 ppb, only 0.5 times the solar abundance and nine times less than the mole fraction found in Saturn. The relative abundance of arsenic in these two planetary atmospheres follows the same pattern found for phosphorous. This similarity may constrain models for the incorporation of heavy elements into the gaseous envelopes of the outer planets. © 1990.
