MEASUREMENT OF N2-COLLISIONAL SHIFT COEFFICIENTS OF METHANE LINES IN THE ν3 BAND AT HIGH TEMPERATURES

Résumé

The study of the spectral parameters, and their variations with temperature and pressure, of methane lines is important for the remote sensing of atmospheres [1]. Methane is a minor component of the terrestrial atmosphere and his impact is important (methane is the third most abundant greenhouse gas [2]). Furthermore, methane is also present in the atmosphere of others planets [3-5] and stellar objects [6,7].

 

In this work, the collisional shift of absorption lines in the ν3 band of methane has been measured for several high temperatures (up to 600 K). This study has been made with a two-beams tunable diode-laser spectrometer.

 

The collisional line shift has been determined using a procedure described elsewhere [8]. So far we know, there is not a general law for the temperature dependence of the collisional line shift commonly used in the literature [9]. Knowing that, different laws have been tested to determine the temperature dependence of the line shift. The observations will be discussed.
