Abstract
Spectroscopic remote sensing in the infrared and (sub)millimeter range is a powerful technique that is well suited for detecting
minor species in planetary atmospheres (Planet Space Sci. 43(1995) 1485). Yet, only a handful of molecules in the Mars atmosphere
(CO2; CO and H2O along with their isotopic species, O3; and more recently H2O2 and CH4) have been detected so far by this
method. New high performance spectroscopic instruments will become available in the future in the infrared and (sub)millimeter
range, for observations from the ground (infrared spectrometers on 8 m class telescopes, large millimeter and submillimeter
interferometers) and from space, in particular the Planetary Fourier Spectrometer (PFS) aboard Mars Express (MEx), and the
Heterodyne Instrument for the Far-Infrared (HIFI) aboard the Herschel Space Observatory (HSO). In this paper we will present
results of a study that determines detectability of minor species in the atmosphere of Mars, taking into account the expected
