High-altitude spectra of Jupiter obtained from the Kuiper Airborne Observatory are analyzed for the presence of germane (GeH4) in Jupiter's atmosphere. Comparison with laboratory spectra shows that the strong Q branch of the ν3 band of germane at 2111 cm-1 is prominent in the Jovian spectra. The abundance of germane in Jupiter's atmosphere is 0.006 (±0.003) cm-am corresponding to a mixing ratio of 0.6 ppb. This trace amount of germane is consistent with chemical equilibrium calculations if the germane present at ∼1000°K is carried up by convection to the spectroscopically observable region at ∼300°K.
