We used two differents spectrometers to measure the breadth of the lines. 1) Linewidths in the fundamental band of CO broadened by argon and nitrogen. The linewidths have been measured for pressures of foreign gases near 1 atm, using a SISAM spectrometer with a very high resolution (the spectral slitwidth was about $0.025 cm^{-1}$). The results are in good agreement with those of Draegert and Williams. We estimate that the relative error of our values is of the order of 3% to 5%. 2) Linewidth in the 3-0 band of CO broadened by itself and by argon, nitrogen and HCL. We used a Czerny-Truner spectrometer with a spectral slitwidth of about $0.070 cm^{-1}$. Various pressures of CO and foreign gases ranging from 1 to 5 atm, were used. Both intensities and widths have been measured using a method of deconvolution founded on the work of Jones and Misell. The relative error of our values is about 5% for pure CO and of the order of 5% to 10% for CO broadened by foreign gases. From the results obtained it appears that except perhaps for pure CO it is not possible to point out a vibrational effect on the linewidths. The theoretical values deduced from Anderson’s theory and including different improvements show that the exchange forces are generally under-estimated. en_US dc.format.extent 144785 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title LINEWIDTHS IN THE 3-0 AND THE FUNDAMENTAL BAND OF CARBON MONOXIDE BROADENED BY FOREIGN GASES en_US dc.type article en_US
