Reflectance spectra from 1 to 6 microns were taken of CH4 and CO2 gas hydrates and were found to be very similar to H2O frost spectra over the entire wavelength region. H2O clathrates have a gas to H2O ratio of about 1/6, hence a surface may contain 17% (by number) gas and appear spectroscopically similar to an H2O frost covered surface. This is important in the pressure-temperature regime of the outer solar system where hydrates, which often have vapor pressures of .00001 (or less) that of the pure gas component, are marginally stable as solids. We may conclude that reflectance spectroscopy (especially earth-based) is useful for positive identification of some components of the surface, but does not set stringent limits for spectroscopically active hydrate forming substances in the presence of water frost.
