Résumé : The results of nitrogen broadening measurements in the ν3 band of 12CH4 using the 5.37 m long absorption path length all-copper Herriott cell were presented. The experimental pressure shift data for 90 and for 140 K temperatures were plotted, where the pressure shift for each component was plotted versus pressure expressed in units of atmospheres. The comparison of values with the values given by HITRAN04 at 296 K show differences of -2.77×10-3cm-1atm-1 in absolute value compared to the database which is largely in the error bar. Absolute differences from 1.9 to 15.3×10-4cm-1atm-1 are observed for the room temperature pressure shift coefficient.
