Abstract

The pressure broadening of CO $J^{\prime}\leftarrow J = 1 \leftarrow 0$ line has been studied by Two different techniques. The investigation was made with the perturber gases $CO^{g}, N_{2}, O_{2}, H_{2}, CO_{2}, 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 $obtained.^{h}$
