Abstract

We confirm the presence of a weak absorption feature in Io's spectrum at 2.125 μm using high resolution observations acquired in 1975 and 1976. If this feature is due to a new class of material on Io, it appears to be the only diagnostic spectral feature of it anywhere in those regions of Io's near-IR spectrum that are accessible at groundbased telescopes. We cannot definitively assign the feature to any atom or molecule.
