Abstract
We report measurements performed at 197, 233, and $294^{\circ}\,K$ of line intensities and broadening coefficients for the $CO_{2}$ transition $201_{III} \leftarrow 000$ around $4854 cm^{-1}$. A total of 109 spectra were obtained for this research by using a Fourier Transform interferometer and a cooled absorption cell. Each of these spectra resulted from co-adding an average of 44 interferograms. The purely vibrational transition moment $|R|$, the Herman-Wallis vibration-rotation Interaction factor F(m) and the total band intensity Band are deduced from equivalent width measurements. Some of the values obtained are: \[ \begin{array}{l} |R^{201}_{000}III | = (0.2064 \pm 0.0017) \times 10^{-2} Debye\\ F(m) = 1+ (0.22 \pm 0.07) \times 10^{-2}m + (0.56 \pm 0.16) \times 10^{-4}m^{2}\\ S_{Band} = 21 329 \pm 69 cm^{-1}km^{-1}atm^{-1}{_{STP}} \end{array} \]
