We present a concept of the Martian multichannel diode laser spectrometer (M-DLS) instrument, a part of the science payload onboard Kazachok landing platform in the framework of the ExoMars mission second stage. The instrument, a laser spectrometer operating in the mid-IR spectral range, is aimed at long-term monitoring of isotopic ratios in main Martian volatiles—carbon dioxide and water vapor—in the near-surface atmosphere. The M-DLS spectrometer utilizes the integrated cavity output spectroscopy (ICOS) technique to enhance an effective optical path length and combines high sensitivity and measurement accuracy with relatively simple and robust design. Provided proper compensation of systematic errors by data post-processing, retrievals of main isotopic ratios with relative accuracy of 1% to 3% are expected during at least one Martian year.

Stabilization Technique

The high resolution spectrum of the 2 υ9 band of HNO3 has been recorded by a tunable diode laser spectrometer with a newly developed frequency stabilization technique. The spectral data were digitally stored and processed by a dedicated micro-computer in order to improve the sensitivity and the precision of the measurements. In addition to the anomalies due to the Fermi resonance with the υ5 = 1 state, we have observed the line doubling caused by the internal rotation of the OH group.

The ν3 vibration-rotation band of cyanoacetylene, HC3N, has been measured in the wavenumber range 2068 to 2095 cm-1 to an accuracy of better than ± 0.005 cm-1 using a diode laser spectrometer. The width of the observed lines is essentially limited by Doppler-broadening. The band center of the ν3 vibration is determined from the observed P- and R-branch transitions to be at 2079.30500 (58) cm-1. The rotational constant of the excited state is B′= 0.151212 (10) cm-1.

The absorption spectra of carrier free 14C16O2 in the spectral range of 2290-2150 cm−1 by a medium resolution FTIR spectrometer, and the spectral region of 2258 − 2229 cm−1 with a high resolution tunable diode laser spectrometer have been recorded. Spectroscopic constants were calculated from the 0001 − 0000 and 0111 −0110 transitions.
