Abstract. Solar occultation observations of the Martian
atmosphere near the limb of the planet were performed
during the P/whos mission by means of the Auguste
infrared spectrometer in the ranges 2707-3740 and
5391-5272 cm ' with a resolving power of 5 1300. The
spectra exhibit features at 2710 and 1730 crn~-' which
have not been identified previously. After applying a
set of corrections to the data and examining the spectra
of various molecules, we are led to conclude that the
best candidate for the above-mentioned features is for-
