| Abstract: |
A re-analysis of thermal emission spectra of Mercury has produced spectra which are similar in overall slope and character to those of other workers, although somewhat more bland in appearance. A previously-reported feature at 11.2 μm has been eliminated or greatly reduced. Our data do not show any reststrahlen band signatures greater than 5%; this finding is consistent with what would be expected from a surface composed of finely-powdered material. We show that assumptions regarding the temperature of the surface of Mercury will influence the appearance of an emission maximum in the 7.5 - 9 micron region. Thus, we cannot claim unambiguous detection of a Christiansen feature at 8.2 μm. |
