Abstract
Several line intensities of the ν 1 + ν 3 ( ∑ u + ) − 0 ( ∑ g + ) bands of 12C 2H 2 and 13C 12CH 2 at 1.533 μm have been revised at room temperature. These molecular transitions were selected to measure acetylene within the framework of the Martian space mission PHOBOS-Grunt. In the spectral region ranging from 6518 to 6530 cm −1, 10 lines of both isotopologues have been analyzed using a high resolution tunable diode laser spectrometer. These transitions are well appropriate to the monitoring of C 2H 2 by laser absorption spectroscopy with standard telecommunication laser diodes. Both the Voigt and the Rautian models are used to fit the molecular line shape and to provide accurate line strengths. Our data are thoroughly compared to existing database (including HITRAN08) and former experimental measurements.
