The absolute intensities of the transitions $401III\leftarrow 000$ and $411_{III} \leftarrow 010 $ of $ CO_{2}$ have been measured from spectra obtained under high resolution. Both the vibration-rotation line intensities and the integrated band intensities are reported. The rotationless transition moment of $401III\leftarrow 000$ is deduced and a vibration-rotation interaction factor $F(m)=1+(4.92\times 10-4)m+(4.4\times 10-7)m2$ is determined. The values obtained are:\ $SBand(401III\leftarrow 000)=(25.54\pm 0.22)10-5cm-2$ $Atm-1(293\circ K$),\ $|R000401III|=(1.87\pm 0.02)10-4Debye,andSBand(411III\leftarrow 010)=(1.83\pm 0.13)10-5cm-2$ $Atm-1(293\circ K)$.
