Abstract Six spectra of Saturn obtained in narrow wavelength intervals near 4.7 μm show evidence for absorption by GeH 4 , which has not previously been detected in Saturn. We find, from comparison with simulated spectra derived from a model atmosphere, that the mole fraction of germane is q GeH 4 ∼ 4 ± 2 × 10 −10 . Similar analysis of spectra of Jupiter demonstrates the sensitivity of our model atmosphere program to the abundance of GeH 4 . The GeH 4 Q branch at 2111 cm −1 appears to be… CONTINUE READING
