The pressure broadening of CO J'<- J = 1<- 0 line has been studied by two different techniques. The investigation was made with the perturber gases CO , N₂, O₂, H₂, CO₂, He, Ne, Ar, Kr, Xe at room temperature.

The two different methods of line broadening measurement and the results obtained in the time- and in the frequency-domain respectively will be discused. Both methods gave results in a good agreement, for example, selfbroadening parameter C_w=3.43(2) MHz/Torr (time-domain) and C_w=3.425(6) (frequency-domain) were obtained.
